AIR FILTER. The air filter is a key component of the engine intake system designed to clean incoming air from dust, sand, small particles and other contaminants before it enters the combustion chamber. This component ensures that only clean air reaches the engine, which is necessary for proper air‑fuel mixture formation and efficient engine operation. The primary function of the air filter is to protect internal engine components such as cylinders, pistons, valves and turbochargers from abrasive particles that could cause premature wear. The filter typically consists of a housing and a replaceable filtration element made of special filter paper, synthetic fiber or multilayer composite material designed to capture contaminants while maintaining optimal airflow. Regular replacement of the air filter helps maintain engine performance, improve fuel efficiency and extend engine life. The catalog includes air filters designed for gasoline, diesel and hybrid vehicles.
