The price of air filters varies from tens to hundreds, depending on what kind of car you are.

1. The air filter is a device to remove particles and impurities in the air. It consists of two parts: a filter element and a shell;
2. Under normal circumstances, the air filter element is recommended to be replaced once at a distance of 10000-15000 kilometers;
3. As time goes by, the clogging of the air filter element will affect the air intake of the engine, which will change the air-fuel ratio in the engine, which will reduce the power of the vehicle and increase the fuel consumption, etc.;
4. Air filter element is a kind of filter, also called air filter cartridge, air filter, style and so on. Mainly used for air filtration in engineering locomotives, automobiles, agricultural locomotives, laboratories, aseptic operation rooms and various precision operation rooms;
5. The engine needs to suck in a lot of air during the working process. If the air is not filtered, the dust suspended in the air is sucked into the cylinder, which will accelerate the wear of the piston group and the cylinder;
6. Larger particles entering between the piston and the cylinder will cause serious "cylinder pull" phenomenon, which is especially serious in a dry and sandy working environment;
7. The air filter is installed in front of the carburetor or the air intake pipe to filter out dust and sand particles in the air and ensure that sufficient and clean air enters the cylinder.
