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.
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.
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. You can also refer to this
The common types of air filters for passenger cars include those using plant fiber filter paper as the filtering medium, represented by European and American car series. This type of filter usually does not contain plastic parts and is more environmentally friendly and green. There are also air filters commonly used in Japanese and South Korean car models, which use non-woven fabric as the filtering medium. Functionally speaking, the two types of filter elements are consistent.
Due to the different designs of various models by the original equipment manufacturers (Oems), the space and technical requirements reserved for air filters also vary, resulting in relatively low universality of air filter elements. Therefore, the design principle of air filters is to make the most of the limited space to meet the various technical indicators of the Oems. Therefore, in the air filter products of MAN brand filters, in addition to the most common rectangular filter elements, there are also trapezoidal, beveled and cylindrical filter elements, etc., truly achieving dedicated use for specific vehicles and tailor-made!
