The car air filter is to filter the dust and impurities in the air. After installation, it can prevent the dust and impurities in the air from entering the cylinder and prolong the service life of the engine.

Air filter function: The air filter is installed at the intake port of the engine. It can effectively filter the dust and impurities in the air, so that the purity of the air entering the combustion chamber is greatly increased, thereby ensuring sufficient fuel combustion. The air filter generally uses a paper filter element, but can it be cleaned repeatedly? In fact, the air filter can be cleaned repeatedly. But pay attention when cleaning: do not wash with water or oil, you should use the dab method and the blowing method. The tap method is to tap the end face of the filter element lightly to make the dust fall off. The purging method is to use the compressed air filter to blow out the inside, but the number of cleanings is limited, because the ability of the air filter to filter air will decrease over time. In this case, the air filter should be replaced.

Car air filter replacement:
1. Remove the screws, bolts or clips that fix the upper cover of the air filter, carefully remove the upper cover of the air filter, and remove the filter element from the air filter housing;
2. Wipe the air filter housing and cover to remove dirt or debris, ensure a good seal, and install a new filter element. Be careful not to let the edge of the filter element tuck between the air cleaner housing and the cover, this may damage the air cleaner and allow unfiltered air to enter the engine due to poor sealing;
3. Install the upper cover of the air filter, and tighten the screws, bolts or buckles. It should be noted that when removing the upper cover of the air filter, do not allow dust or debris to enter the upper cover of the air filter and its upper cover. This can cause engine damage, and using an incorrect air cleaner element can cause severe engine damage.
