The definition and function of air filters

Filtering air impurities: The air filter can effectively capture solid particles in the air, such as dust, sand grains, and insects, preventing these impurities from entering the engine.
Improving engine efficiency: By ensuring the air drawn in by the engine is clean, the air filter can help the engine operate at the optimal air-fuel mixture ratio, thereby enhancing combustion efficiency and boosting power.
Reduce emissions: Clean air helps with more complete combustion, thereby reducing the emissions of unburned fuels and lowering the production of harmful gases, which meets modern environmental protection requirements.
Protecting sensors: Many modern engines are equipped with various sensors in the intake system, such as air flow sensors (MAF). The function of the air filter ensures that these sensors operate in the best condition.
