Air filter for VAZ 2109 - how to change and how to choose

Replacement frequency

Replacing the air filter is necessary every 15-20 thousand km. It is recommended to periodically blow out the filter element with compressed air. However, sometimes it may be necessary to unscheduledly replace the filter. Symptoms of the need to install a new consumable are:

noticeable loss of power from the power unit;
the car had to cover a long stretch of dusty dirt road;
fuel consumption has increased;
the previous replacement period is unknown, for example, when purchasing a used car;
There is a lot of oil getting into the air filter;
The filter element has noticeable mechanical damage, which does not allow quality air purification.

VAZ 2109 owners are often faced with the situation of oil in the air filter. The reason for this is the design of the crankcase gas exhaust. The tube connects the power unit crankcase and the filter housing. This design reduces air pollution and increases engine efficiency.

Oil can flow through the crankcase ventilation tube into the filter. To solve this problem, car owners recommend closing the hole in the filter housing with a champagne cork. The crankcase outlet can be extended with a hose of suitable diameter.

Replacing the cabin filter VAZ-2114

Experts recommend replacing the cabin air filter element 7–8 thousand kilometers after each installation of a new one. But if the car is operated under heavy road dust, the filter should be changed more often. This will provide the most comfortable conditions inside the vehicle.

Signs that the air filter element is clogged and needs to be replaced:

the presence of foreign and unpleasant odors inside the cabin: mold, dust, exhaust gases and others;
weak air flow from the external air supply ducts when the fan is running at full power;
intense and frequent fogging of windows;
insufficient heating of the interior by car heater in winter.

The VAZ-2114 cabin filter is made in the form of a plastic frame on which the filter element is fixed. It is located under the cover of the car heater fan housing, which stands under the hood near the windshield in the center between the wings close to the bulkhead separating the engine compartment from the passenger compartment. It should be noted that the manufacturer did not install cabin filters on the first batches of the VAZ-2114. To determine its presence, simply press on the cover (jabot) of the stove fan housing. If there is no filter element, the plastic of the casing will bend freely. When you feel the elasticity of the lid, it means the salon cleaning element is in place.

Air filter replacement sequence:

Unscrew the 2 screws securing the cover on both sides of the fan housing.
Remove the cover.
We remove the old one and install a new air filter element.
We perform the reverse steps to disassembly.

How often should you change the cabin filter?

A dirty and clogged filter not only contributes to the formation of an unpleasant odor in the cabin, but also reduces the service life of the heater fan motor. Therefore, replacing the cabin filter of the VAZ 2109 must be done on time. The filter installed inside the cabin well protects the inside of the car from plant pollen, and this reduces the likelihood of an accident. This is due to an allergic reaction of dust to a driver suffering from such a disease. When you sneeze, you lose control of the car, which can lead to an accident. The filter instructions indicate signs of product replacement:

The air flow is greatly reduced, which leads to poor interior cooling in summer and unsatisfactory heating and fogging of the windshield in winter.
The cabin filter usually has the shape of a rectangle, and is located in a frame or without it.

Tip: The filter color is most often snow-white, but some are impregnated with activated carbon, after which they acquire a gray tint

Therefore, when choosing a product, you should not pay attention to its color. You need to change the cabin filter as it becomes dirty, but several times throughout the year.

You need to change the cabin filter when it gets dirty, but several times throughout the year.

Tip: If, after installing a new cabin filter, unpleasant odors have not disappeared, you need to pour chemicals into the air ducts that will force the dirt out. If the result is unsatisfactory, it is necessary to choose a mechanical method - complete disassembly of the system and manual cleaning.

How to replace the cabin filter of a VAZ 2109 can be seen in the video. Timely replacement of the element will create comfortable conditions for the movement of passengers and the driver in a VAZ 2109 car. The price of human health is not compatible with the price of any device in the car.

We remove the carburetor air filter on a VAZ 2109 car in order to subsequently replace it with a new one or to blow it with compressed air if it is very clogged or to perform other work in which its presence will interfere with us. The air filter is located in a metal housing, which in turn is attached to the carburetor cover with four nuts. To replace the filter housing and the filter element itself, perform the following sequence of actions:

We remove the housing cover; to do this, unscrew the nut that secures it, located in the center, then unfasten the four spring clips and remove.
Remove the filter element from the housing, either blow it out with compressed air if it is not very dirty, or replace it with a new one. The second option is much better.

Next, we need to disconnect all the pipes from the body, namely the crankcase ventilation system pipe coming from the cylinder head cover; to do this, we loosen the clamps securing it.
The body itself is attached to the carburetor cover with four nuts, which we need to unscrew using an eight-size wrench. We unscrew the nuts carefully so that they do not fall into the air chambers of the carburetor. Having unscrewed the nuts, remove the metal gasket, rubber seal and the filter housing itself along with the rubber pipe.
The opening of the carburetor air chambers must be closed either with a special technological plug or a piece of clean material, especially if you removed the filter for a long time.

This completes the process of removing the VAZ 2109 carburetor air filter housing. Carry out the necessary repairs, then reassemble in reverse order. Before assembly, check the condition of the rubber sealing gasket, which must be replaced if damaged. Also check the quality of fastening of the studs on the carburetor cover, as they sometimes tend to loosen. Tighten them if necessary. To tighten them, screw two nuts securing the filter housing onto the threaded part and, tightening these nuts together, tighten the stud itself.

Air filter 2109. Pan. Dimensions. Correspondence.

I made a pyramid out of plasticine, placed it in the air purifier body, buried the lid, and snapped the latches.

Pyramid (approximately).

He pulled out the crumpled pyramid and measured it. Measurements were taken three times.

Measuring a crumpled pyramid 1.

Measurement of crumpled pyramid 2

As they wrote in the magazine Behind the Wheel No. 6 for 2002, “ONE THIRD FILTER” is the nominal height of the air cleaner housing (60 mm). But checking the height of real bodies on different cars showed that “off-scale” heights of up to 63 mm also occur.

Additional measurements:

The height of my case closed only with “latches” (the nut is not tightened) is 64.5 mm.
The height of my case, closed with latches and a screwed nut, is 63.65 mm.
In my case, a tightened nut (I have a wing nut) gives a maximum pressure of 1 mm.
Not every normal filter will work properly on any car. The fact is that the current OST 37.001.491–90 prescribes a height for filters (59–63) ± 1.5 mm. In other words, everything that falls within the range of 57.5–64.5 (scatter is more than 10% of the filter height) is considered normal.
In general, it became clear that we either need to take filters from 65 mm. height, either change the pan, or make a rubber gasket under the filter.
In the same “Behind the Wheel” test, domestic filters did not shine with quality, so I looked at what I could choose with a height of 65 mm. from import.

I didn’t dig particularly deep, but it turned out that there weren’t many options.

Height of different filters

As a result, I bought a MANN C2443/1. Honest 65 mm. with a slight plus. I took it from ISNEXT (formerly EXIST).

As for the FRAM CA660PL filter, despite the manufacturer’s stated height of 61 mm, my copy has a height of 57-58 mm. The currently installed “Behind the Wheel” filter is 63 mm.

I bought the filter at EMEX. So it’s hard to say whether it’s a defect or a fake.

Well, here's a comparison photo between MANN and FRAM. Feel the difference!
