Car engines require sufficient airflow to operate. This rectangular air filter, with model number 07K129620, functions like an efficient "gas mask," precisely installed within the engine's intake pipeline. Its primary role is to filter out harmful particles—such as dust and sand—before air enters the engine combustion chamber. The elongated design ensures more even distribution of air as it passes through the filter, significantly enhancing airflow efficiency while increasing the filtration area and adsorption capacity.
