Which spark plugs for Niva 21214 injector are better?

Replacing spark plugs and setting the gap

For stable operation of the Niva 2121, 21213, 21214 injection and carburetor engines, it is necessary to change the spark plugs on time, since they are an integral important part of the engine that ignite the combustible mixture

There are more positive reviews, of course, in the more expensive price category, as well as with platinum or iridium rods, which exceed the service life of simple ones by 70-80%, and need to be changed not after 20 but after 100 thousand km. which increases service life by 5 times.

How to set the spark plug gap in the field:

For carburetor Niva 2121 this gap is - 0.9 mm For injector 21214 - 1.11 mm

Insert a feeler gauge of the required size into the spark plug and tap it with a hammer if the gap is large, or lift it with pliers if it is small.

The next step is cleaning, clear the wells of debris so that nothing gets into the block.
We unscrew the old spark plugs, counterclockwise; if they are stuck, use Wd40 and repeat after 15 minutes.
We install new spark plugs with the correct gap in the engine.

If there is black soot deposits on the core, this means that the fuel you are using is of poor quality, or oil is getting into the combustion chamber, this may be due to worn piston rings, valve guides, oil seals. If soot covers the core together with the body, this indicates a disruption in the supply of the fuel-air mixture, we recommend checking the carburetor settings and changing the air filter. If the core is white, the ignition adjustment is incorrect. A melted core is the reason for the overheating of the car, so if your Niva is boiling over a couple of times, we recommend checking the spark plugs and paying attention to whether the engine is behaving differently, this happens, of course, extremely rarely, but forewarned is forearmed.

Service

To keep the spark plugs in good working order for as long as possible, service them every 10,000 thousand km, clean them with a brush and adjust the gap if necessary.

Which spark plugs are best for VAZ 21214 injector 8 valves?

» Other »

Question for experts: what should be the spark plug gap for a VAZ 21214 injector.

Best regards, Anderson Kaygorodov

Best answers

You can't go wrong with a 1.1 injector!! ! on some foreign cars even more clearance is needed!! !

And in winter, the gap is reduced to 0.8 mm since the air density is greater, which means the resistance too! This is from the VAZ 2115 operating manual and applies to all injection VAZs!

Answers from experts

Nothing. the gap is larger and forward.

I didn’t even think, I twisted the first ones I came across!!!!

They are all the same, both for the injector and for the carburetor.

No, that's possible. It is dangerous to put diesel spark plugs on the injector and vice versa.

If the heater is the same then drive until you buy it. set the current gap to 1

It's a joke? Candles are not divided into such subcategories.

Candles differ in heat rating. By thread diameter. Along the length of the threaded part.

But that there were special “carburetor” ones - this is the first time I’ve heard of them. I'm probably way behind.

Manufacturers

Engine diagnostics based on the condition of the spark plugs. Inspection of the spark plugs can help you identify some engine malfunctions without contacting a special service center.

Particular attention should be paid to the appearance and color of soot. The normal condition of a spark plug that does not require replacement is moderate burnout of the electrode, a complete absence of oil stains, as well as a minimal amount of soot and coffee-golden deposits on the insulator. In this case, the Chevrolet Niva does not require constant topping up of oil and does not frighten the owner with a brutal appetite

In this case, the Chevrolet Niva does not require constant topping up of oil and does not frighten the owner with its brutal appetite.

If you find black carbon deposits and dry soot on the center electrode, most likely your car is consuming much more fuel than you would like. The reason may be a malfunction of the air damper drive mechanism or injector, or a clogged air filter.

In general, this indicates a failure in the engine management system. A light gray or white color of the electrode means it is overheated, which ultimately leads to burnout of the exhaust valves.

You may have selected the wrong spark plugs or are using fuel with too low an octane rating. The engine is healthy - so are the spark plugs. The red skirt of the central electrode is the result of using an excessively large volume of additives containing metal in gasoline.

Metal deposits during prolonged use of such fuel can form a conductive coating on the insulation, causing the spark plugs to fail. This means that it got from the engine into the cylinder.

The reasons are incorrect selection of spark plugs, wear of valve guides, valve stem seals or piston rings. As a result, the Chevrolet Niva consumes much more oil than usual.

https://youtube.com/watch?v=zIbel_Ki9is

If on the central electrode and its skirt you find a dense layer of oil with particles of cylinder destruction and drops of unburnt fuel, it means that one of the valves is damaged or the partition between the piston rings is broken. As a result, engine power weakens and fuel consumption doubles. In this case, a full-scale renovation is necessary.

A completely destroyed central electrode and its skirt are the result of using defective spark plugs, long-term engine operation with detonation, or the use of low-octane fuel.

The cylinder head will require major repairs. Ash deposits on the electrode indicate the wear and tear of the oil scraper piston rings, and the destruction of the ceramic insulator indicates a faulty spark plug or its mechanical damage.

Erosion of electrodes occurs when using leaded gasoline, and flooding of spark plugs with fuel occurs when the ignition system or injector is faulty.

Types of spark plugs for a Russian SUV Original Bosch spark plug So, you have carried out diagnostics and come to the conclusion that your car does not require repair. Which spark plugs to choose if you only need to replace them?

A spark plug with a central electrode coated with platinum. When you install ordinary spark plugs, through thousands. In this case, four-pin ones.

I will not repeat the nonsense that is said in stores and markets. It was a completely different SUV, but then this was confirmed in our cars. Their main advantage is starting the engine in the morning in very cold conditions.

In summer they are ordinary, in winter they are multi-contact. Candles are made in Germany. Spark plugs Niva Chevrolet and Niva.

The tightening torque must correspond to that specified by the manufacturer. This means that work can also be done in unfavorable environments where the temperature is elevated. If the heat value is low, this means that the SZ is hot and will often overheat.

What to look for when choosing candles

If it overheats, it will not last long. Size plays an important role, that much is clear.

If its size is small, the part simply will not screw into the socket and then the electrodes will be at a great distance from the combustion chamber. If the length is longer than necessary, then the electrodes will stick out, and this increases the risk of contact with the piston.

When choosing, it is best to use the instructions from the car, which will tell you which spark plugs to install in the Chevrolet Niva. In addition, knowing the exact size, you can choose the best heat rating (author of the video - VanLe9).

Inspection and replacement of parts

To carry out diagnostics, you will need a special wrench for turning it out. Please note that it is better to inspect the spark plugs after the engine has been running for a long time, for example, after a long trip on a country highway. If you have never replaced this small but important part in a Chevy Niva before, follow these simple tips.

A plug that produces the correct spark.

Remove the high-voltage wire tips from the spark plugs.
Clean the part and the area around it so that when turning it out, dirt does not get into the cylinder.
Using a wrench, remove the spark plugs from the cylinder head.
Examine the candles. Based on the degree of carbon deposits, its color and character, you can diagnose the engine and determine whether it is worth changing the part, buying gasoline at another gas station, or whether it is time to repair the cylinder head.
Use a round feeler gauge to check the gap between the electrodes. It should be 1-1.15 mm.
If necessary, bend the side electrode and adjust the gap between the electrodes. Be careful: under no circumstances should the central electrode be bent! This can lead to damage to the insulator and inevitable failure of the spark plug.
Reinstall the candles. To do this, first screw them all the way by hand, and then tighten them with a wrench. Do not overdo it!

Can spark plugs be long lasting and require no maintenance?

Theoretically, yes, because modern cars often have enough spark plugs, even for more than 100,000 kilometers. However, you need to be aware that, regardless of even their ideal condition, you need to replace them according to the manufacturer’s instructions - usually about 30,000 kilometers. For platinum parts, replacement is recommended, usually after 120,000 km.

You can check the condition of the spark plug during a routine inspection. When buying spare parts, you should be aware that specific spark plugs are suitable for a particular engine, and it is quite difficult to find universal parts. Do not believe the assurances of a car mechanic who assures you that the spark plug of another car will match yours. This can ultimately lead to damage to the motor and additional repair costs. You can buy new spark plugs at Niva21. They must comply with the vehicle manufacturer's recommendations.

What do candles do?

As you know, a spark plug supplies a spark to the cylinder to ignite the fuel inside the combustion chamber. The spark plug is exposed to enormous temperatures, which of course does not have a favorable effect on its condition, so neglecting to replace spark plugs is highly discouraged and, if possible, it is advisable to change them before winter for easier starting in cold weather.

A worn-out spark plug can cause a lot of trouble, such as a lot of engine tripping, a number of misfires, loss of power and even an increase in fuel consumption.

LADA spark plugs: top 10 options

The rating contains 10 modifications of spark plugs, without division into specific car models.

10th place: ZZ A17 DVRM

The list of the best offers opens with an effective model that is in demand among a large number of buyers. Such prevalence is ensured by the stable quality of products. In the original packaging it is impossible to find a defective part or a spark plug with a broken gap. A significant advantage of the products is the ability to work actively even when the voltage drops to 6V in the on-board network. Similar spark plugs in the VAZ 2107 are often found due to their moderate cost.

The indicators are overshadowed by bad statistics - as of 2020, 35% of the kits on the market are fakes, which forces motorists to carefully select products in stores.

simple design.

plenty of fakes.

9th place: TZ 17 DVRM

The next representative of the rating implies the presence of as many as three electrodes on the working part of the device. A large number of motorists install such spark plugs on a VAZ carburetor or even an injection type. Thanks to the use of advanced developments in design, the manufacturer has increased the service life of the electrode.

Pirate copies also play a role here - there are a large number of them, which makes buyers cautious about purchasing products.

good performance;
long period of operation;
wide use.

8th place: DENSO W20EPR-U11

If you want to buy VAZ injector spark plugs, you can turn to the eighth position of the rating. Candles represent a compromise between high quality and moderate cost. Thanks to this symbiosis, such spark plugs are perfect for the VAZ 2106. Also, this model will be relevant for more modern versions. It uses technology to increase spark stability. The development significantly increases the service life of the part, which helps save on vehicle servicing. This also made it possible to reduce the maximum voltage drop to 6.5 V, which is less than that of Russian analogues, but thanks to stability, the spark plugs win positions.

stable operation during voltage fluctuations in the on-board network;
long service life.

7th place: BRISK LR15YCY-1

The next contender for the title of best is distinguished by an increased overhang of the working part. The specified spark plugs for the VAZ 2107 carburetor are ideal. The standard eight-valve engine works great with the included model.

In terms of performance parameters, the model is a confident average and can be used even on used foreign cars with similar engines. The ability to work on a dead battery has also been developed. The product is capable of igniting the mixture even at 6.2 V within the network, which is significantly better than the performance of competitors’ analogues. Buyers consider the rather high cost to be the only serious disadvantage.

Spark plugs for Chevrolet Niva and Niva

The topic of this review is Chevrolet Niva and Niva spark plugs, using the example of the German manufacturer Bosch. There are similar lines from other manufacturers, but since I am currently working with this manufacturer, I will tell you using the example of its products.

spark plugs for the Niva family

Spark plugs Niva Chevrolet and Niva. Correct installation

Several general questions that Papuan services either “forget” or never knew about. The tightening torque must correspond to that specified by the manufacturer. The metal sealing ring should not turn into foil when tightened, otherwise it will cease to perform its function. It is advisable to install the spark plug with copper, aluminum or ceramic lubricant, especially in our case when we have an aluminum cylinder head.

There is no need to pour lubricant as much as you can; one drop on the threaded part is enough so that next time the spark plug does not “stick” and can be easily unscrewed. Now about gasoline and spark plug life. Don’t think that if you installed a new set, you will run on the spark plugs until they die naturally. ONE “left” filling is enough so that a set of candles can be thrown into the trash. And of course the quality of gasoline itself.

In St. Petersburg we have a network of “red-colored” gas stations; it happens that a couple of gas stations are enough for the spark plug to turn red; naturally, this “pattern” cannot be penetrated by any spark, leading to the breakdown of the ignition module.

Manufacturers

A little about the manufacturers. I can name several companies that produce spark plugs for Chevrolet Niva and Niva. These are Champion, Eyquem, Beru, Denso, Valeo, NGK. A few words about NGK. I used the products of this manufacturer for a long time until “small” problems began. A new set of spark plugs was installed on the car, and after a couple of thousand, one spark plug would “fly out” and the engines would start to stall. So I bring candles not only for myself, but also for several diagnostic companies, statistics have appeared, this phenomenon has become common. Without being lazy, I sent several sets to the Moscow representative office.

They diplomatically answered me: I’m a fool, the candles are tightened with the wrong tightening torque. Well, they sent it nicely)) Having waited until NGK held a seminar in Russia, I went and laid out everything to the “real Japanese”. Having made a thousand Japanese apologies, in a private conversation, he said that for the sake of competitive prices, the production of the cheap segment of candles was transferred to other factories. But the percentage of defects is within normal limits and sellers and services need not worry. And if something happens, then send the defect to the representative office for examination. The circle is closed.

Since 2011, I began working with products from German manufacturers Bosch and Beru.

Why did you change the wires? Having problems with the ignition?

yes, and the problems remained, but it was noticeably better; the wires were of some kind, I changed them “just in case, so that I know when and what I replaced them with” anyway, then I’ll replace them with an elephant or a blue silicone adze

Reg.: 07/15/2008 Messages: 39 From: Donetsk Age: 34 Car: 21214i 2007 color: deep sea.

Well, if we are to give links to auto magazines, then from the ZR conference: Quote: Before installation, you should check and, if necessary, set the gap recommended by the car manufacturer: for a carburetor engine 0.7 mm, for an injection engine 1.1 mm. For VAZ-2112 engines, manufacturers often offer spark plugs with gaps that differ from those recommended by the car plant, usually 0.7-0.8 mm. Therefore, before installation on the engines, you should again set the gap required by the car manufacturer to 1.1 mm.

Just understand that the spark plug manufacturer does not test how these spark plugs will perform on every car they make. This check and selection of spark plugs is carried out by the car manufacturer themselves. And who do you personally trust more: those who conducted the relevant tests, or those who simply release their product? Moreover, the required spark plug gap is determined by the design of the ignition system, and not by the spark plug model. That is, if such and such a gap is recommended for some spark plugs for a particular engine, then for all other spark plugs the gap should be the same.

Expert recommendations

None It is important to consider some differences when choosing a SZ:

EZ A17DVRM consists of Russian-made parts;
APS A17DVRM consist of German-made parts.

To avoid confusion, you should always look closely at the markings. Speaking about the second option, one must also take into account the fact that APS A17DVRM are manufactured using advanced technologies. Among other things, they are distinguished by better processing of the electrodes, and therefore you can avoid problems with a running spark, which is typical for defective devices.

When choosing suitable products, you need to follow some rules:

DENSO IW20 and NGK devices contain a sufficient amount of iridium, which has a beneficial effect on engine life.
BOSCH WR78X parts accommodate four electrodes.
GM WR8DCX are suitable for use in winter and summer. They are preferable to the aforementioned A17.

The best manufacturers for Chevrolet Niva

If you are about to replace the spark plugs, then you need to know what to put on the injector of your car. Among all the options currently presented on the automotive market, the leader for the Chevrolet Niva can be considered the Bosch Platinum WR7DPX products, which have a gap of 1.1 mm.

Spark plugs Bosch Platinum WR7DPX

Due to the fact that they are popular, fakes are very common. When installing low-quality spark plugs on a car, its engine will begin to perform noticeably worse, fuel consumption will increase, and problems with the operation of the power unit will begin to appear. It is better to initially purchase high-quality original parts, since over time it will be quite problematic to detect a fake.

The Japanese DENSO W20TT are also very popular. They have numerous advantages:

excellent quality;
presence of a powerful spark;
stable engine start.

Spark plugs DENSO W20TT

Of course, if spark plugs provide benefits on one engine, they may have a negative effect on another.

That is why it is important to select them taking into account the characteristics of a particular vehicle and the recommendations of the vehicle’s operating manual

The service life of conventional spark plugs ranges from 20 to 30 thousand kilometers.

It is very important to replace them regularly and not drive them for more than the allotted time. Otherwise, this may result in negative consequences for the system - lead to failure of high-voltage wires and the ignition coil

NGK spark plugs

You can find out which spark plugs are better for a Chevrolet Niva using the list below. Speaking about the best manufacturers, we need to mention BOSCH PLATINUM WR7DPX spark plugs with a gap of 1.1 mm. Due to their popularity, they are copied, so you can find many fakes on the market. If you install such an option in a car, engine performance will noticeably decrease and problems will begin. The catch is that the symptoms do not appear immediately, so identifying a fake is not so easy.

There is another great option - NGK spark plugs. These spark plugs for Niva Chevrolet injector, like the previous ones, are iridium. The key to the success of iridium SZs is that when purchasing them, you can get rid of thoughts about problems with them for a long time. To install iridium and platinum products, unfortunately, you will have to disassemble half of the engine. In return, they reduce acceleration time and increase the rated power of the engine.

So, to summarize, what is good for one engine may be bad for another.

So I bring candles not only for myself, but also for several diagnostic companies, statistics have appeared, this phenomenon has become common. Without being lazy, I sent several sets to the Moscow representative office. They diplomatically answered me: I’m a fool, the candles are tightened with the wrong tightening torque.

But the percentage of defects is within normal limits and sellers and services need not worry. And if something happens, then send the defect to the representative office for examination. The circle is closed. Since 2011, I began working with products from German manufacturers Bosch and Beru.

The best candles for Niva

Based on reviews from forums, it has been repeatedly revealed that Nivovody gives their preference to NGK candles. These spark plugs are excellent for the Niva engine and can withstand high temperature loads. NGK spark plugs make it easier to start the engine in cold weather and even reduce fuel consumption due to their structure. The closest to standard spark plugs and suitable in design to the Niva engine will be NGK No. 11 spark plugs.

These spark plugs easily overcome the 30,000 km barrier without any damage.

Engine diagnostics based on spark plug condition

Checking your spark plugs can help you identify some engine problems without having to visit a specialist service center.

Particular attention should be paid to the appearance and color of soot. The spark plug is in normal condition and does not need to be replaced.

moderate burnout of the electrode, complete absence of oil stains, as well as a minimal amount of soot and golden-coffee deposits on the insulator. At the same time, the Chevrolet Niva does not require constant refueling and does not frighten the owner with a fierce appetite.

If you find soot and dry soot on the center electrode, chances are your vehicle is using a lot more fuel than you'd like. The cause may be a malfunction of the air damper or injector drive mechanism, or a clogged air filter. In general, this indicates a failure in the engine management system.

The motor is fine. spark plugs are also working properly

Red skirt of the central electrode. the result of using excessive amounts of metal additives in gasoline. With prolonged use of such fuel, metal deposits can form a conductive coating on the insulation, which will lead to failure of the spark plugs.

Found traces of oil? So, it moved from the engine to the cylinder. Causes. incorrect selection of spark plugs, worn valve guides, valve seals or piston rings. As a result, the Chevrolet Niva consumes much more oil than usual.

If you find a thick layer of oil on the central electrode and its skirt with particles of cylinder destruction and drops of unburned fuel, it means that one of the valves is damaged or the partition between the piston rings is broken. As a result, engine power is reduced and fuel consumption doubles. In this case, a complete repair is required.

Ash deposits on the electrode indicate the development or appearance of oil scraper piston rings, and the destruction of the ceramic insulator indicates a defective spark plug or its mechanical damage. Erosion of the electrodes occurs when using leaded gasoline, and filling of spark plugs when the fuel ignites occurs when the ignition system or injector fails.

DIY replacement instructions

To dismantle, first of all you will need a special key for removing the SZ. First you need to remove the ends of the wires from the spark plugs and clean all contacts from dust. The entire spark plug and the area around it must be thoroughly cleaned to prevent debris from getting into the cylinder.

Next, you need to remove the devices with a key and visually diagnose them for damage. You need to inspect both the electrodes and the threads. If there is noticeable darkening on the NW, it’s okay, but if there is no brownish coating, you should be alarmed.

If black plaque is found, it must be removed. It indicates that engine oil has entered the engine cylinder.

When replacing, be sure to check the gap on the new SZ. If it doesn't quite fit, you can carefully bend the electrode on the side. This is a rather risky method, because you need to be as careful as possible and not damage the central electrode. Otherwise, the SZ will fail. After preparing the socket for the SZ, you need to insert it and tighten it with your fingers, and then tighten it with a wrench. Be careful here, otherwise the thread may break.

Types of spark plugs for Russian SUV

Most often, spark plugs are used, which are recommended for 8-valve injection engines. The optimal gap between the electrodes is 1.1 mm. It is necessary to ensure that it does not exceed 1.5 mm, otherwise the spark plugs will fail. Low-quality fuel will also be detrimental to them. Advantages: low price, long service life.

Multi-contact spark plugs are ideal for the Niva Chevrolet, which is actively used in severe frost conditions. The main advantage is trouble-free engine starting early in the morning. These candles can only be used in winter and replaced with regular ones in summer.

Expert recommendations

Niva Chevrolet injector with VAZ-2123 engine are equipped with A17DVRM spark plugs. This plant, despite the fact that it is located in Russia, belongs to Bosch. These German manufacturers have proven themselves well in the market.

It is important to consider some differences when choosing a SZ:

EZ A17DVRM consists of Russian-made parts;
APS A17DVRM consist of German-made parts.

When choosing suitable products, you need to follow some rules:

DENSO IW20 and NGK devices contain a sufficient amount of iridium, which has a beneficial effect on engine life.
BOSCH WR78X parts accommodate four electrodes.
GM WR8DCX are suitable for use in winter and summer. They are preferable to the aforementioned A17.

Selection options

No one has yet invented standard SZ that are suitable for absolutely all cars, so it is clear that on a Chevrolet Niva you will have to select devices based on two indicators:

heat number;
geometric size.

The first indicator indicates the operating temperature of the product. The higher the value, the colder the product. This means that work can also be done in unfavorable environments where the temperature is elevated. If the heat value is low, this means that the SZ is hot and will often overheat. If it overheats, it will not last long.

Size plays an important role, that much is clear. If its size is small, the part simply will not screw into the socket and then the electrodes will be at a great distance from the combustion chamber. If the length is longer than necessary, then the electrodes will stick out, and this increases the risk of contact with the piston. When choosing, it is best to use the instructions from the car, which will tell you which spark plugs to install in the Chevrolet Niva. In addition, knowing the exact size, you can choose the best heat rating (video author - VanLe9).

It is recommended to replace it every 30 thousand, and the recommended imported analogue is the BRISK Super LR15YC spark plug, or LR17YC - this is for winter. However, in terms of price/quality ratio, there are now more interesting options. At one time, one authoritative publication compared 9 replacement options. But the reader will not immediately know which spark plugs work best on a Chevrolet Niva: if you buy the “best” BOSCH Platinum spark plugs, cold starts will become problematic.

We watch a video with conflicting reviews about NGK brand products.

It’s worth noting right away that not a single manufacturer has yet created a spark plug option that will fit any engine. Each motor has its own model. This must be taken into account if the time has come to change them. When selecting the optimal option, two most important selection criteria should be taken into account:

Heat number is the temperature value for efficient operation. The higher this indicator, the colder the part remains during the operation of the car. This parameter demonstrates the ability to operate effectively in the most unfavorable environment - at high temperatures. The lower this indicator, the more often the part will overheat. This significantly reduces its service life.
Geometric size - different brands and models of cars use a certain type of spark plug, which has its own thread length, number of electrodes, and size of the spark plug key.

Without knowing which spark plugs are best for a Chevrolet, it is recommended that you read the vehicle’s operating instructions. It clearly states the size and type. Knowing them, it will be possible to select options with the optimal heat rating.

New spark plugs will help get rid of many problems with your car.

Good afternoon everyone, I would like to hear feedback on the use of various spark plugs in our cars. Who is “lighting” which ones and what’s the catch?

I’ll start with myself - I bought the car with EZ A17DVRM immediately after running it in (2 thousand km), changed it to BPR6ES11, 10 thousand became unstable XX. Changed it to DENSO W20TT - now 31 thousand km. — the engine works well.

However, winter is coming. Maybe it needs to be changed - who will say what? I myself am looking towards multi-electrode ones: either BERU Ultra X or BERU Ultra X Platin or BERU UXT6

or W20EPBR-S - I doubt them and the gap of 0.85 is too small for the injector, or NGK BUR6ET - similar problem with the gap.

The most, the very thing that is needed. (V-Line #13). Only here it is impossible to find something that is not a fake. I think maybe they haven’t yet learned how to fake its more expensive analogue? BPR6EIX11

I found a sign about the applicability of these spark plugs for our cars https://www.technicsavto.ru/site/?part=prim_ngk

Engine 1.6 carb OZONE, new wires are not oak (700 rubles). gas station 92. company 2000 I’ll tell you from personal experience.

1) Brisk candles - 170 rubles (4 pieces), in winter they start the car -30, the car runs well, the mileage of the candles is short, they quickly fail. Replace every 2000-5000. They are very afraid of soot. 2) Champion candles (Champion) - 330 rubles (4 pieces), start the car the same way - 30, the car runs exactly the same, The mileage of the candles is average, replacement every 5000, although I change 1 candle at a time due to carbon deposits, I just throw it away. Although it could be a candle OK.

I put the brisk together with the champion, they work the same way. It’s not a fact that brisque dies quickly, I used briskies mainly in winter. The consumption is the same. PS: You can clean the spark plugs with a can (Carburator Cleaner)

Is it okay that zebin means “gasoline” in English? but from candles with the inscription “GAZ” I would run headlong

I will never believe that a “sliding” spark with a serviceable spark plug (without soot or defects) occurs.. Landsberg’s physics textbook
