Should I change the air cabin for car maintenance?

Function of air grille: The air grille is installed at the air inlet of the engine, which can effectively filter the dust and impurities in the air, greatly improve the purity of the air entering the combustion chamber, and thus ensure the full combustion of fuel.

Working mechanism: the air bag is composed of paper filter screen, which seems to be simple in structure, but its function can not be underestimated. The failure of air cabin will lead to insufficient gasoline combustion, insufficient engine power, pollution of throttle body, unstable idle speed and abnormal engine jitter.

Price: The price of the air cabin of the general model is between 50~ 100 yuan, and the price of a few special models such as Jaguar, Mercedes-Benz and BMW is above 100 yuan. The price of accessories is generally 1/3~ 1/4 of the price of normal parts, and it is only twenty or thirty yuan at most.

Suggested replacement time: every 20000 kilometers of the car.
