The car engine is a very precise part, and the smallest impurities will damage the engine. Therefore, before entering the cylinder, the air must first pass through the fine filtration of the air filter. The air filter is the patron saint of the engine, and the condition of the air filter is related to the life of the engine.
If the air filter is not cleaned and replaced, the car will lead to insufficient engine intake during driving, so that the fuel combustion is incomplete, resulting in unstable engine work, power decline, and increased fuel consumption. Therefore, the car must keep the air filter clean.
Under normal road conditions, the air filter must be replaced when the car travels 8000-10000KM. In areas with large dust levels, the replacement interval should be shortened accordingly.
