Regardless of the make and model of the vehicle, each car is equipped with a similar set of parts that make up a single design. One of these auto parts is an air filter. The corresponding auto spare part is a kind of mechanism through which the atmospheric air is purified from dust, dirt and other micropollutant particles entering the car engine. The importance of an air purifier cannot be overestimated, since such a relatively small, and at first glance mediocre, part of the vehicle performs a number of functions that ensure the smooth functioning of the engine and the car as a whole.
Novice car enthusiasts do not always take this part of the car seriously, however, this is not true. You should be aware that the air filter becomes dirty over time and ceases to perform its main functions, so it is important to regularly check the condition of the air cleaner and, if necessary, replace the corresponding part. This publication will discuss the timing and features of replacing the air filter on VAZ models such as 2110 and 2112. In addition, information will be provided on the nuances of replacing the air cleaner on a car with an injector and the consequences of untimely replacement of the filtering auto parts.
The role of the air filter in the operation of VAZ cars of the tenth model
The importance of this element in the operation of the internal combustion engine is not worth talking about again. Even the person farthest from automotive topics understands that without an air purification system, the VAZ 2110 engine will not work for very long. Special paper purifier gaskets not only ensure high-quality combustion of the fuel mixture, but also guarantee long-term operation of the mass air flow sensor (MAF), in modern VAZ cars the injector type is responsible for the correct ratio of the fuel-air mixture.
A clogged air filter of VAZ 2110 (2112) cars greatly affects the power developed by the internal combustion engine, because the amount of air passing per unit time becomes insufficient for elective combustion of fuel . Of course, the electronic control unit (ECU) and mass air flow sensor are also responsible for the ratio of the volumes of gasoline and air in the fuel-air mixture, but this entire system in VAZ 2110 and 2112 cars can function effectively only with a working purifier. Therefore, you should never forget about its timely replacement.
How it all happens
During the operation of the car, the engine consumes a large volume of purified air and, gradually, the filter element becomes clogged. At the same time, the degree of contamination is influenced by the conditions in which the car is operated.
Replacing the air filter VAZ 2112
Basically, manufacturers set the optimal resource of this element at 10-15 thousand elements for VAZ cars with a round element used in VAZ 2101-2107 and 2108-2109 cars. Subsequent models, starting with the VAZ 2110, are equipped with an air filter with an established service life of 30 thousand kilometers, indicated on the filter element cover.
Note. However, it is not recommended to strictly adhere to these rules and replace them before the specified parameters.
In cases where the machine is operated in harsh climatic conditions (sandy terrain, high dust levels), the air filter must be replaced 1.5-2 times more often than the recommended replacement period. For car owners, modern replacement of the filter element is not burdensome compared to the costs of expensive repairs of more complex units that fail due to normal contamination of the air, fuel or oil system.
Note. If, during the maintenance of the machine, ruptures or other mechanical damage are discovered on the filter element, then you should not try to repair it, postponing replacement until “later”. A damaged filter must be changed urgently.
Frequency of replacement of the VAZ 2110 air filter
According to the manufacturer's recommendations, on VAZ 2112 cars the air filter must be changed every 30 thousand kilometers. However, you should not be too literally attached to this number. If you often drive on country roads and excessively dusty roads, the air purifier will last half as long. Therefore, the terms in each individual case are individual and 30 thousand can be considered only the extreme upper limit, suitable for fairly gentle working conditions.
Replacing the VAZ 2110 air filter
The VAZ air filter is less susceptible to clogging in winter. At this time of year, you practically don’t have to worry about its operation, because the amount of dust in the air is minimal. In any case, the product is inexpensive, and you can change it in just five minutes literally on the go, so there’s no point in delaying its replacement.
Among beginners, a very typical mistake is often made when installing a VAZ 2110 - 2112 filter in a car. Many people think that the position of the filter plates should be directed perpendicular to the air flow, although the image on the product body suggests the opposite. Thus, of course, the VAZ 2110 (2112) filter still allows air to pass through, but with increased resistance. As a result, the engine loses power and fuel consumption increases.
You should also not forget about the culture and cleanliness of garage repairs. When changing the VAZ 2112 filter, don’t be lazy, vacuum its body to remove any remaining dirt and debris, because a considerable part of the dust remains there. And then, for sure, it will be possible to say that your car works like new.
When is it necessary to change?
The main purpose of the air filter is to clean the incoming air flow from the surrounding air from dust, dirt, pollen and other contaminants. Paper, foam rubber, felt or cloth can be used as a filter material. There are special zero resistance filters that allow you to increase engine power by 3-5%. It makes sense to install a zero filter on sports cars.
Zero resistance consumable
Over time, any filter, including zero-resistance filters, becomes dirty. The service life of the filter element is affected by the degree of environmental pollution and operating conditions.
When the filter element becomes dirty, the following problems arise:
- the throughput of the filter material decreases;
- fuel consumption increases;
- the quality of the fuel-air mixture entering the cylinders deteriorates;
- Engine power drops.
From a dirty consumable, abrasive particles can enter the cylinders and damage the surfaces of rubbing parts.
To eliminate the problems that have arisen, it is necessary to either clean the dirty element or replace it with a new one. The advantage of a zero-resistance filter is the fact that it is enough to wash the product with a special composition and it restores its properties.
It is advisable to replace it after 15,000 kilometers. When operating a car in a metropolis or rural area with dirt roads, it is better to replace it after 5-7 thousand kilometers.

Choosing an air filter for VAZ 2110
Having once again visited a VAZ spare parts store, a motorist may well be blindsided by the range of air purifiers offered there for cars of the 2010 and 2012 models. More than 15 different brands of both domestic and foreign manufacturers are ready to protect your engine from dust and dirt. They all have beautiful labels, they all seem to be very good-looking and generally great. Are you sure you know how to make the right choice?
Although there are products on the shelves with a very wide price range, buying a filter for a VAZ 2110 (2112) is a simple thing. The most affordable offers cost about 80 or 90 rubles, and for the most prestigious product items, sellers will ask you to fork out 350-400 rubles. Of course, the cost of even the best cleaner is not particularly high. You may even find it easier to pay the maximum and not bother. In fact, not everything is much more complicated and interesting.
Original air filter VAZ 2110
Let's first determine what criteria can be used to distinguish a good VAZ air filter 2010 and 2012 models:
- nominal resistance to the passage of air;
- quality of filter elements (dust transmission coefficient);
- service life under given operating conditions (air dust content up to 9.4 g per cubic meter and air flow up to 160 cubic meters per hour).
The most durable cleaners were the following brands: Mann, Hengst, Big, the well-known Bosch and Mahle. Moreover, if the Boshevsky filter will cost us a pretty penny, 400 rubles, then the “Bigovsky” product costs about 100 rubles, all other things being equal. So tell me, is it worth overpaying in this case?
“Big” also has the lowest dust transmission coefficient, expressed as a percentage of its total mass. By the way, the VAZ 2112 injection air filter from Consol is very good in this regard. It is also inexpensive, 100 rubles, but has a slightly shorter service life. However, it is also a very attractive choice.
Types and principle of operation
The design of the filter is quite simple. If it is an injection motor, then the filter elements are made in the form of squares with a gill-like structure. And a special material traps dirt, dust and other particles of debris at the entrance to the system.
Gill-shaped filter structure
Today there are a large number of so-called sports air filters on the market. Manufacturers assure that they are able to reduce air resistance to a minimum and increase the power of the power unit. In fact, the difference between regular and “sporty” elements is practically zero. But the latter can cost 10 times more than a standard VAZ filter.
How does this very element work? Let's try to figure it out.
- First, the filter is installed in front of the engine compartment and fixed on supports.
- Air is sucked in through the intake pipe. This pipe is located under the filter.
- The pumped air goes through the filter elements, passes through the air flow sensor, pipe and intake hose.
- Then it passes into the receiver, the intake pipe and directly to the cylinders, where the air-fuel mixture is formed.
Replacement
Replacing the air filter on a VAZ 2112
To carry out the work you will need the following materials and tools:
VAZ 2112 air filters
On carburetor VAZ cars of the 8th and 9th series with a round air filter installed, it is replaced in the same way. Replacement is carried out as follows:
- First you need to open the hood and get close to the air filter housing;
- Then the three nuts are unscrewed to remove the air filter cover. This may require a key at “10”;
- After this, the nuts are unscrewed, the 4 spring clips are snapped off, the cover is removed and set aside;
- The filter element is taken out.
Note. Quite often you can see traces of oil on the filter element, this means that the engine throws out oil along with crankcase gases, which reduces the engine life of the filter. In such cases, it is necessary to install a crankcase oil trap, which you can buy in a store or make yourself, since the oil in the air filter can play a cruel joke on a VAZ 2112.
By the way, on a VAZ 2112, the oil in the air filter pipe also indicates the mandatory installation of an oil trap.
VAZ 2112 air filter
- After removing the used element, it is necessary to thoroughly wipe away the debris and dust remaining at the bottom of the case;
- After performing a number of necessary operations to remove dust and dirt, a new air filter, previously purchased at the store, is installed. For mild contamination, in some cases the filter can be blown out with compressed air and reinstalled.
VAZ 21124 air filter
Note. There is an additional filter strip on the outside of the filter. Some drivers throw it away when installing the filter, but there is no harm from it, although there is little benefit, so removing or leaving it is at your own discretion.
- The filter element is placed in the housing and covered with a lid. Everything is assembled in the reverse order of disassembly, quite simply and quickly.
Zero resistance filter
Some car owners change the standard filter to the Federal Tax Service. This element has a different shape (resembling a mushroom) and is installed directly at the outlet of the air pipe. To install such an element in a car, you need to completely remove the plastic filter housing. After this, secure the FNS terminal with the rubber pipe using a clamp.
Why is it important to install such a filter? This is explained by the fact that the Federal Tax Service has a large throughput. This has a positive effect on engine power. But as practice shows, the expected increase is no more than two horsepower. Along with this, the filter requires periodic cleaning, and not with a simple cleaning agent, but with oil impregnation. To make the Federal Tax Service less contaminated, the owners place it in a round metal case. But this does not significantly increase the interval between cleanings.
Reasons for high fuel consumption on VAZ
- Dirty air filter.
- Inappropriate tire pressure.
- Dirty fuel filter.
- Low fuel pressure.
- Oxygen sensor malfunction.
- Vehicle speed sensor malfunction.
- Low compression.
- Low quality gasoline.
Sometimes you can solve the problem of the huge fuel consumption of the VAZ-2114 yourself. First of all, you need to check the degree of contamination of the fuel filter and check it for debris. If there is debris inside it or suspicion of contamination, then it is better to replace it. This element is inexpensive, and its average price is 300 rubles. You can replace it yourself - it’s simple and does not require the intervention of a specialist.
The second filter is the air filter. Air passes through it, which is subsequently mixed with gasoline and supplied to the combustion chamber. And if it is dirty, it will not be able to pass enough air. As a result, the air-fuel mixture will not be enriched with oxygen, and a lean fuel mixture will quite logically lead to increased gasoline consumption. Car owners often manage to reduce gasoline consumption by approximately 3 liters per 100 kilometers simply by replacing the air filter. It's easy to change - it's in a large black box under the hood.
However, if the sensor breaks down, the system warns the driver about this with a “Check” light on the dashboard. You can also see the error using the on-board computer. Often this sensor breaks down due to poor quality gasoline, oil getting into the combustion chamber, or valve clamping.
- Speedometer failure or interruptions.
- “Floating” idle speed.
- Noticeable loss of traction.
- Stopping the engine when idling.
- Increased gasoline consumption.
The crankshaft position or timing sensor is also called a phase sensor. It determines the engine operating cycle and generates a signal depending on this. Such a sensor is not installed on all VAZ cars. If it malfunctions, a “Check” will light up on the dashboard, and in addition to increased gasoline consumption, there will be a drop in engine power, fuel detonation in the combustion chamber, and engine stoppage in neutral gear.
