The air filter element cannot be changed all the time. First of all, the filter element functions to filter out dust and sand particles in the air, and to ensure that sufficient and clean air enters the cylinder. If it is not replaced for a long time, the air filter cannot effectively filter the suspended particles in the air. The engine will accelerate wear and carbon deposits, shorten the service life of the engine, and if it is serious, the phenomenon of "cylinder pulling" may occur. Therefore, it is very important to replace the air filter element regularly.

Car air filter function:
1. The air filter filters the air to prevent dust from entering the engine and affect the fuel combustion in the engine;
2. The air conditioner filter filters the air to make the air entering the cab clean. However, the filtering level of the current air conditioner filter element is not high, and dust can still enter the car air conditioner and then enter the cab;
3. It is very necessary to replace a high-efficiency air-conditioning filter element. It is directly related to our health;

Replacement steps of the air filter:
1. First loosen the filter lock and remove the fixed nut;

3. Then you can replace the new filter element. But it should be noted that you cannot touch the paper part of the filter element with your hands, especially not to allow oil to contaminate the filter element;
4. Finally, install the components in the reverse order of disassembly.
