The air filter is mainly to filter the dust and various impurities in the air entering the cylinder block, so that the automobile engine can have a good working

environment. Generally, the air filter needs to be replaced once when the car travels 10,000 to 20,000 kilometers.

The function of air filter

1. The air filter ensures that the gas entering the car cylinder is clean. If air with impurities and dust enters the cylinder, it will cause poor driving power of the car

and reduce the driving experience.

2. Especially in relatively dry environments, car air filters can play a more effective role. If there is a problem with the air filter, it may cause particles to appear in

the car's cylinders and pistons. If the situation is very serious, it can also cause the car engine to experience cylinder pulling.

How often do I change the air filter

Generally speaking, the air filter of a car needs to be replaced every 10000 to 20000 kilometers. The main reason is that it is easy for dust to enter the car during

driving, so the air filter needs to be adsorbed. If the time is long, the air filter will produce a lot of particles and dust, and even affect the piston and engine life of the

car, leading to the need to replace the engine.
