The air filter is responsible for cleaning impurities from the outside air (dust, pollen, etc.) before it enters the engine to mix with the fuel. This function is crucial to protect the internal components of the engine, such as cylinders and pistons, from premature wear. A filter in good condition ensures efficient combustion and optimal vehicle performance.
