Air filter: Located in the engine intake system, it consists of two parts: the housing and the filter element. Passenger vehicles are usually equipped with a first-stage filtration
system (i.e., without pre-filtration). Dust and other impurities in the air entering the engine are mainly intercepted by the filter element to ensure that a sufficient amount of clean air enters the cylinder. The filter element is a vulnerable part and needs to be replaced and maintained regularly.
Why is it necessary to filter air?
The engine generates power by drawing in a large amount of air and burning fuel. If unfiltered air enters the engine, impurities such as dust and sand suspended in the air will be sucked into the cylinder, causing wear on the piston assembly and the moving parts of the cylinder, as well as the "cylinder pulling" phenomenon. At the same time, it will interfere with or damage sensitive components such as air flow meters, release incorrect signals, and lead to problems such as incomplete combustion and excessive emissions.
How often should the air filter be replaced?
The original factory-quality air filter element can refer to the replacement cycle in the original factory maintenance manual. Generally, for passenger vehicles, it should be replaced every 15,000 to 20,000 kilometers. If frequently driven in harsh working conditions (such as dusty roads, construction sites, etc.) or areas with poor air quality, it should be replaced no more than once every 10,000 kilometers. Experienced car enthusiasts will keep it within the safe range of 7,500 to 8,000 kilometers.
