The air filter serves to clean the air entering the engine for further use in preparing the fuel mixture. The quality of the filter is ensured by two parameters - the degree of air filtration and air flow resistance. Both parameters are related - the better the air filtration, the greater the resistance, as a rule, and vice versa.
The entry of dust and other particles along with air into the combustion chamber is unacceptable; they can cause an abrasive effect and lead to premature wear of rubbing parts. A decrease in filter throughput, due to its contamination, among other things, reduces the dynamic characteristics of the engine, leads to excessive enrichment of the mixture with fuel, increases fuel consumption, reduces power at high speeds, and reduces throttle response.
When choosing an air filter, you need to look for the “golden mean” of these parameters. There are enough tests and reviews on the Internet regarding various brands of air filters, I will not dwell on this.
Avto-VAZ recommends replacing the air filter every 30 thousand kilometers. This likely involves driving on clean paved streets that are shampooed every few days.
On our roads, filters need to be changed much more often - operating conditions are far from ideal.
Alternatively, you can take out and clean the filter at certain intervals, but I do not find this effective - the micropores of the filter material will remain clogged.
The previous filter for my car was purchased in haste. I had to go through the Shaumyan Pass and I understood that the dust that was present in abundance there would completely kill the old filter and I would have to look for a new one on the road.
Unfortunately, at that moment I could not find a filter from manufacturers known to me and, on the recommendation of the seller, I purchased something without identification marks in a plastic bag. External inspection did not raise any comments, despite the absence of any markings. The filter was successfully installed and forgotten for a while.
Time has passed, and with it 5 thousand kilometers - the time has come to replace the stranger with something more famous.
A BOSCH filter S 9061 1 457 429 061 was purchased.
Open the hood. The rectangular black air filter housing is located next to the radiator grille. We disconnect the wiring block from the mass air flow sensor (mass air flow sensor) - it will interfere with us in the future. The connector latch is located at the bottom of the block - you need to press on it and pull the block to the side.
- Then you need to unscrew the 4 bolts holding the cover using a Phillips screwdriver.
Carefully lift the lid and at the same time bend the corrugated air duct. We take out the old air filter - it is held on by a rubber seal.
It is difficult to assess the degree of filter contamination by appearance. It is clear that dust is present.
We clean the air filter housing from dust and debris.
Foam inserts cannot be removed. If they come off, they need to be glued back in place. They serve as emergency water absorbers to prevent it from entering the combustion chamber through the filter, which can cause water hammer.
Pay attention to the inscriptions in the filter housing - the filter must be installed so that the corrugations are located along the car body. We install the filter taking these recommendations into account.
- We check the tight fit of the filter rubber to the edges of the housing and close the top cover, gently pressing the filter.
- All that remains is to tighten the four bolts securing the cover and reconnect the mass flow sensor harness block.
- The very first trip with the new filter showed an improvement in engine performance - the car became more responsive.
- Everything that was written above is true for all injection VAZ cars - the replacement method and the filter itself are identical.

Replacing the air filter on Lada Priora: Replacement instructions
The air flow filter of your Lada Priora is designed to purify atmospheric air and then supply it to the engine cylinders to form a fuel-air mixture.
The efficiency of air purification in the filter is affected by two indicators: the amount of air purification and the resistance of the filter element to air flow.
These indicators are inversely related to each other: higher quality of air purification implies difficulty in its passage through the filter.
If the air filter allows tiny particles of dirt and dust, which are found in abundance in the atmosphere of large cities, to pass through, they can cause serious damage to the inner surface of the engine cylinders and the working surfaces of the pistons. The fact is that road dirt and dust consist of small grains that have good abrasive properties and can scratch surfaces.
On the other hand, a decrease in the throughput of the filter element causes “oxygen starvation” of the engine and it significantly loses its designed power.
Good filter elements intelligently combine the ability to effectively purify atmospheric air flow and ensure that sufficient air enters the engine cylinders to form a mixture.
When choosing an air filter, you need to look for the “golden mean” of these parameters. There are enough tests and reviews on the Internet regarding various brands of air filters, I will not dwell on this.
Concern Lada recommends changing the filter element after 30 thousand kilometers. But in reality, the service life of the air filter can be extended if you drive through clean meadows and forests, or shortened if you navigate through city traffic jams in the dirty atmosphere of big cities.
Step-by-step instructions for replacing the air filter on a Lada Priora
The air filter in the Prior is located in the engine compartment, near the radiator grille. To gain access to the filter box, you need to unplug the mass air flow sensor connector.
Please note the foam stakes. Check their condition, if necessary, glue and dry them, as they are intended for emergency water collection.
Install the replacement filter element, following the inscriptions on it.
Screw the 4 screws and connect the MAF connector.

The importance of the purifier is not exaggerated
The normal cycle of the Priora's 16-valve power unit involves ignition of the working mixture in the combustion chamber. This mixture consists of air and injected fine gasoline. The very first stroke of the Lada engine is intake. The intake valve opens and air enters the cylinder. At the same time, fuel is supplied through the injector.
Next, the piston rises and a compression stroke of the combustible mixture occurs. Under pressure it ignites and pushes the piston down. The crankshaft rotates and torque is transmitted to the wheels. The quality of the explosion in the chamber determines the impulse transmitted by the connecting rod to the shaft, and, accordingly, the power of the power unit. This is how the motor works correctly.
The engine will not operate at full power in some cases.
- The filter is clogged and does not supply clean air in the required quantity.
- The cleaner allows dust and dirt to enter the cylinders.
- The cleaner is wet and water enters the combustion chamber.
The main indicators of filter quality are the degree of filtration and air flow resistance. These parameters depend directly on each other. With more filtration, the purifier will have better resistance.
Ignition will be of high quality if the required amount of air and fuel enters the cylinder. When one filter is used for a long time, it becomes clogged and some of the air is trapped on the curtains. The lack of air in the combustion chamber will have to be compensated with excess fuel. This is why there is increased consumption. And even then, the force of pressure of the piston on the connecting rod will be less than with air, which leads to a decrease in power.
Providing clean air to the cylinders is the responsibility of the air filter.
It consists of corrugated cardboard in the form of curtains that stop particles of dust, dirt, and, if necessary, water on their way to the engine. The entry of solid particles into the cylinder liner disrupts the lubrication system and increases the abrasiveness of the crank mechanism parts. And water that gets into the chamber changes the composition of the combustible mixture, and safe ignition is under the threat of water hammer.
How to replace the air filter on a Lada Priora without going to a service station
Replacing the air filter in Lada Priora with your own hands
The purpose of the air filter is obviously to clean the air necessary to prepare the fuel-air mixture entering the combustion chamber. However, in addition to its benefits, the filter produces resistance, which reduces engine power. An air filter that is too tight will result in a drop in power and unnecessary fuel consumption.
A filter that is too weak, on the contrary, will allow dust and grains of sand into the combustion chamber, the impact of which on the surface of the chamber will lead to wear of the rubbing parts.
Therefore, it is important to choose a good Lada Priora air filter, the density of which is sufficient to avoid the ingress of foreign particles and not have a negative impact on the dynamics of the engine.
Replacing the air filter is recommended every 30,000 kilometers, however, if the need arises earlier, you should not wait for serious negative consequences.
Required tools:
- new air filter;
- crosshead screwdriver;
- vacuum cleaner.

Filter models - analogues
Air filters produced by the following manufacturers are suitable for the VAZ 2170 Priora:
- Nordfil - AN1014;
- TSN - 9140;
- Filtron – УТ000072199;
- Motor-superUT000072199;
- Bosch - 1 457 429 061;
- Knecht (Mahle Filter) - LX 220;
- Fram - CA3399;
- Kolbenschmidt - 50 013 059.
Filters from these manufacturers are sold at the same price. Their quality can be assessed by the “mesh”: if it is too dense, it will create air resistance, and the volume entering the injector will noticeably decrease - fuel consumption will increase again, Priora will not be so fast and dynamic.
How to remove the air filter housing on a Lada Priora?
This element serves, as the name implies, to purify air coming from the external environment and direct it directly to the car engine. Air filters of many new domestic (and not only) car brands are very similar to each other; finding them under the hood is not difficult.
The air purification filter is a black plastic box with a streamlined shape - while it shows a corrugation or a rather thick tube that leads from the filter to the motor.
In Lada Priora, this filter is located in the center of the hood right at the front of it and is mounted on rubber supports.
- Usually the filter is removed for replacement if it has become deformed or simply due to external influences (the appearance of severe cracks, for example), as well as to change the filter element located inside.
- To remove the air filter housing, prepare a 10mm wrench and also some pliers just in case.
- Using a 10mm wrench, loosen the nut of the “–” terminal of the battery.
Remove the “–” terminal from the battery.
A mass air flow sensor is connected to the air filter, which serves in the car to determine the exact amount of air, and based on the data of which the car’s electronic control unit will calculate the proportions to form the fuel mixture. This sensor is attached to the air filter by a wiring harness. To remove this harness, push up the latch (it is yellow).
Use a screwdriver to loosen the metal clamp on the air outlet pipe of the air purification filter.
Next, carefully disconnect the pipe from the air filter housing.
Please note that the rubber housing supports described above (there are three of them in total) are installed in the metal body of the machine and when you try to remove the filter housing, they will try to pull out along with it. To prevent this from happening, lubricate all three supports with a silicone-based lubricant.
If, nevertheless, the rubber supports came out at the moment when you pulled out the filter, simply install them back in their place. This can be done by clamping the ends of the supports with pliers.
The filter takes in air from below, for which another pipe connects to it. Therefore, when removing the filter housing, carefully begin to pull it up until the inlet pipe appears from below - pull it and disconnect it from the filter housing; You don't need to remove any clamps for this.

Priora fuel system
• gas tank; • pump and filter located in the tank; • fuel line; • pressure regulator; • fuel rail; • four nozzles; • throttle valve; • intake manifold; • electronic engine control system.
The work is based on the fact that when the ignition is turned on, the electric fuel pump starts working, which builds up pressure in the rail. Further, when the engine is cranked by the starter, the electronic control unit opens and closes the injectors, the air-fuel mixture enters the combustion chambers, according to the operating diagram.
After fuel enters the combustion chamber, a spark is formed between the electrodes of the spark plugs. The fuel ignites and the engine starts. The injectors are electromagnetic valves, and the control unit is responsible for their operation. He is also responsible for the quality of the mixture, the ratio of air and gasoline. Sometimes problems arise and you have to disassemble the fuel system for repairs.
Replacing the air filter on Lada Priora
The air filter performs two essential, but at the same time opposite functions, namely: it cleans the air entering the vehicle engine and passes the required amount of purified air into the engine cylinders. In addition, the air purifier promotes the formation of a fuel-air mixture, which, when it enters the combustion chamber, increases the power of the car. However, if the specified filtering auto parts are not replaced in time, the air filter will not be able to perform its job properly, which will lead to significant damage to the vehicle, including engine failure.
Thus, you should pay attention to the importance of the air cleaner in the overall mechanism of the car and emphasize the importance of timely replacement of the air filter.
The article proposed for study will provide information on how to replace the air filter on a Lada Priora car with your own hands, rules for choosing a suitable part, and also indicate the timing of replacing the corresponding part.
When to change?
To extend the life of the vehicle, it is advisable to regularly check the condition of the air filter.
When the first signs of damage to the air filter of a car part or its contamination appear, the air cleaner should be replaced.
In accordance with the information specified in the Lada Priora operating instructions, the frequency of replacing the filter element is 30 thousand kilometers.
Depending on the situation, replacing the air purifier may be necessary earlier, so there is no need to strictly follow the indicated indicator.
This is due to the fact that each car owner uses the Lada Priora car with different intensity and under different conditions.
For example, if you frequently drive a car or drive off-road and in rural areas, the air filter will become more quickly contaminated with dust and other microparticles than when driving a Lada Priora on city roads.
If for some reason you do not have information about the timing of replacing the air cleaner on your Lada Priora, it is worth remembering the signs that appear when the filter element is dirty and, therefore, not working properly.
Signs of replacing the air filter on a Lada Priora:
- The amount of fuel consumption has increased. In normal condition, the 16-valve Lada Priora engine functions due to the penetration of the optimal amount of purified air and fuel into the cylinder. When the air cleaner is clogged, air is retained, and its deficiency in the combustion chamber is compensated by consuming additional volumes of fuel;
- There is a loss of vehicle power. This manifests itself in difficulties when starting the car, poor acceleration;
- The appearance of exhaust gases indicates the need to replace the air filter on the Lada Priora;
- Extraneous noises are heard when the vehicle is operating.
The appearance of at least one of the presented symptoms does not necessarily indicate the need to replace the air filter. Each of the signs presented may indicate problems with other parts of the car, so it is recommended to regularly maintain the car in order to avoid serious and financially expensive breakdowns.
How to change?
It was previously mentioned how important a part such as an air filter plays. If you do not replace the air filter on the Lada Priora in time, this error can cause serious malfunctions in the operation of the car’s engine.
For example, this is expressed in an increase in fuel consumption or a loss of vehicle power.
In addition, when particles of dust and dirt enter the combustion chamber, carbon deposits will form, which, settling on the inner surface of the cylinders, will scratch the reservoir and the working surfaces of the pistons.
Before replacing the air filter on a Lada Priora with your own hands, you should pay attention to the following recommendations:
- It is important to carefully consider the purchase of a new air purifier, since choosing the wrong air-filtering auto parts will, on the contrary, harm the operation of the Lada Priora and, in addition, increase financial costs;
- When replacing the air cleaner on a Lada Priora car, you need to pay attention to the presence of lubricating fluid in the air filter. If there is oil on the surface of the filtering auto part, this indicates weak compression, a clogged breather or loss of elasticity of the oil caps;
- Before installing the air purifier, it is necessary to check the tightness of the filter element in the housing, and also check for defects in the part.
The procedure for replacing the air filter on a Lada Priora does not take much time and, moreover, is quite simple to perform. Even an inexperienced car enthusiast can cope with replacing an air filtering car part, but only after familiarizing himself with the intricacies of the operation and step-by-step instructions.
Required list of tools:
- New air filter, suitable in all respects for Lada Priora;
- Waste fabric;
- Set of screwdrivers (flat and Phillips).
How to choose an air filter?
To extend the life of the vehicle and the air filter in particular, you can clean the air purifier yourself. To do this, it is necessary to remove the contaminated filter element from the housing, rinse with water and wipe dry. However, it is not recommended to abuse this advice.
Firstly, if you frequently wash the part accordingly and if it comes into contact with water, sooner or later the air purifier of the Lada Priora car will still perform its functions worse. Secondly, such cleaning of the air filter leads to disruption of the fuel combustion process, which means that in the future this may also affect the operation of the engine.
Where are the fuses located in the car?
The relay and fuse box is also called the mounting block or black box. In the event of a car breakdown related to electrical equipment, the fuses and relays are first checked. If a fuse is blown, you must first determine the cause of its blown before replacing it.
- The main mounting block of the Priora is closed with a lid and located at the driver’s left foot. To open it, you need to turn three latches 90° and unclip the lid.
- The fuse box is under the hood, which is located near the expansion tank.
- Another mounting block, which is located near the left foot of the front passenger. To gain access to the fuses and relays, unscrew several screws with a Phillips screwdriver.
If you look at the diagram, you will notice that the cigarette lighter fuse is designated F13
How and when to change the cabin filter in LADA Priora
The air conditioning systems of Lada Priora cars use cabin filters. The purpose of the devices is to effectively clean the air flow entering the car interior. Below we will look at how to replace the cabin filter on a Priora and in what cases it needs to be changed.
Before changing the purifier, you need to know its location.
A device designed to filter the air in Lada Priora cars is installed in a special niche in the engine compartment under the windshield of the car.
The cleaner is placed vertically, so to gain access to it you need to remove the hood seal. The location where the filter is located does not depend on whether the car is equipped with air conditioning or not.
When is it necessary to change?
Now let's look at how often you need to replace the purifier in the Lada Priora.
According to official regulations, the old filter must be replaced with a new one every 10 thousand kilometers if the vehicle is used under normal operating conditions.
When they are harsher and you often drive your car on dusty roads in large cities, then you need to change the cleaner every 5-7.5 thousand kilometers.
By what signs can you determine that it is time to make repairs and install a new cabin filter:
- the air inside the car has become dirty;
- car windows sweat a lot, even in dry weather and no humidity outside;
- a damp smell appeared in the car interior, which intensified when the heating system was activated;
- the glass blowing became weaker.
Filter selection
Lada Priora cars can use several different cleaners - Panasonic and Halla.
Filter care
To maintain optimal engine performance, filter elements must be replaced periodically. The regulations established by AvtoVAZ recommend installing a new cleaner every 30,000 km of the Lada. But the factory figure is slightly different from reality. With intensive driving on dirt roads, dusty cities, rough terrain, the filter on the Priora may not be enough for 30 thousand km. This is an approximate number, and the frequency of changes on a particular Lada depends on operation.
You can slightly extend the service life by removing and cleaning the filters manually. But at the level of micropores, particles still remain on the curtains. After manual washing, water particles may remain on the cardboards, even if it seems to you that everything has been wiped dry. In this case, an attempt to extend the life of the purifier leads to worse fuel combustion.
Cleaners are produced by different companies, and accordingly their quality. You should not buy a device in a nameless package without a manufacturer's mark. It's better to spend a little more, but be sure that the device will last a long time.
The highest quality filters: Bosch, SCT, Mann, BIG. They are also the most expensive. The domestic Nevsky and Salyut are not much inferior in quality. But the price is more reasonable.
Features of removing and installing the air filter on the Lada Priora
During the operation of a vehicle, the air filter suffers the most, because it is responsible for purifying the air coming from the external environment.
Most brands and models of cars, regardless of the country of production, are equipped with parts of a similar structure. Finding them under a car hood is not difficult.
Below we will tell you how to properly install an air filter on a Lada.
Part Features
The Priora air filter is presented in the form of a small black plastic box with a streamlined shape. Upon visual inspection, you can distinguish a corrugation and a wide pipe, which is directed towards the engine.
The Lada Priora air filter is located in the central part of the hood, directly in the front area, and contains 16 valves. The external environment has a detrimental effect on it - chips and cracks appear.
In most cases, this unit must be dismantled for updating due to deformation or replacement of cleaning elements.
The air filter is attached to the metal base using rubber supports.
Regularly checking and installing the air filter is an important step that should never be skipped. If the housing breaks down, there is a possibility that air flows will enter not only the motor, but also through the cracks formed. Stones can get into such holes, which will subsequently be directed into the engine. For this reason, the integrity of the cleaning part and the box is important.
Installing the air filter takes only 15-20 minutes, after which the engine runs much better. Manufacturers recommend replacing and installing a new block every 30,000 kilometers traveled.
List of tools
Replacing the air filter on a Priora is carried out using the following tools:
- wrench (10);
- screwdrivers of various modifications;
- pliers.
After preparing the necessary instruments and components, you can safely begin to consider the procedure for dismantling and replacing the unit.
Before removing the part, we recommend disconnecting the negative terminal from the battery. This is done using a wrench.
Step-by-step instructions for high-quality dismantling
The air filter on the Priora is connected to the mass air flow sensor. This component is necessary in a vehicle to determine the correct amount of air flow.
Based on such information, the electronics unit responsible for control calculates the correct proportions for fuel preparation. The air filter is attached to this unit using wires.
To remove the wiring harness, lift up the special clamp. Most often it is colored yellow.
Next, using a screwdriver, you need to loosen the steel clamp that tightens the outlet tube from the filter. With leisurely movements you can disconnect it from the box.
The air filter on the Priora has three rubber supports that are connected to the metal body of the car. During dismantling, they can also be pulled out.
To prevent this, the air filter mount (rubber supports) can be lubricated with automobile oil or a silicone mixture.
If the air filter mounts in the form of rubber supports have come out of their grooves, you can return them to their place using pliers. Use pliers to pinch the ends of the supports and place them in the grooves.
Air flows enter from below through a special pipe. During the dismantling process, carefully pull the housing upward until the input element appears. Pull the pipe and it will detach from the body.
The instructions on how to correctly install the air filter after changing the component are characterized by the reverse sequence of actions.

About refilling the air conditioner
You need to pump 500 g of refrigerant into the Priora air conditioner. Until 1995, R12 freon was pumped into air conditioners, but it was considered toxic due to its high fluorine content. Therefore, R134A freon is now in use. Preparing for refueling looks like this:
- special cleaning foam from a can is pumped into the air conditioner radiator;
- the radiator closes. The car engine starts and idles. At the same time, the air conditioner turns on. It must run for at least 15 minutes so that the foam passes through the entire recirculation system;
- vacuum is performed. A pump is connected to the air conditioner, which removes air from the system along with foam and moisture.
Refueling
To refill the air conditioner, the driver must purchase a metrology station and a can of freon.
The station is a system of hoses, adapters and pressure gauges connected to the air conditioner.
- The station hose is connected to the low pressure fitting on the air conditioner pipeline (it is usually painted blue or has the English designation “low”).
