The air filter is a very important part of the car, which can filter the air entering the engine and prevent dust and impurities from damaging the inside of the engine. The correct maintenance of the air filter can ensure the normal operation of the engine and extend the service life of the engine. The following are some suggestions for maintaining the air filter:

Regular inspection:
It is generally recommended to check the air filter every 5,000 km to 10,000 km.
When driving in dusty or heavily polluted environments, the inspection interval should be shortened.
Clean air filter:
If the surface of the air filter is not very dirty, you can use low-pressure compressed air to blow outward from the inside of the filter to remove the attached dust.
Do not clean paper air filters with water, as water may damage their filtration structure.
Timely replacement:
When the air filter is very dirty or damaged, it should be replaced immediately.
The replacement cycle is generally 20000 km to 40000 km per drive, and the specific replacement cycle is recommended by the vehicle user manual.
Use qualified air filters:
When purchasing, choose the air filter produced by the regular manufacturer to ensure the filtration effect and service life.
Pay attention to sealing:
When installing the air filter, ensure that the seal ring between the filter and the intake pipe is intact to prevent unfiltered air from entering the engine directly.
Avoid using oil soaked air filters:
In order to increase the filtration effect of the air filter, some drivers will soak it in the oil, which will hinder the flow of air, but not good for the engine.
Through the above maintenance measures, you can ensure that the air filter works in the best condition, provide clean air for the engine, and ensure the power and economy of the car.
