filter out dust and impurities at the same time to ensure high air volume，further improve fuel efficiency，reduce fuel consumption，extend engine life.
The air filter
is one of the most important filters in both gasoline and diesel engines. Depending on performance levels, a commercial vehicle engine draws up to 2,400 m³ of air per hour, with a particle content of up to 50 mg/m³. HengYouquality filters permanently remove foreign particles from intake air and maintain safe and long-lasting engine performance. In addition, they ensure optimum fuel-air mixture levels and thus ensure the best possible combustion.
