CF21160/1 MANN Filter Secondary Air Filter

MANN Filter's CF21160/1 Secondary Air Filter is a crucial component in maintaining engine health. Installed within the engine’s air intake, this filter effectively removes contaminants from the air stream. This ensures cleaner combustion, improves engine efficiency, and supports long-term durability. Manufactured in Germany, it measures 610 x 230 x 230 mm. Dimensions are provided by the supplier and may include packaging dimensions. Air filters are critical engine components situated between the air intake and throttle body, preventing abrasive particulate matter from entering the engine. Constructed typically of pleated cellulose or synthetic media, they provide a large surface area for maximizing airflow while trapping contaminants as small as 5 microns. Filter efficiency is rated by percentage of particle capture, influencing engine performance and longevity. Variations include paper, cotton gauze, and non-woven synthetic materials, each offering differing airflow and filtration balances. Proper sealing via gasket or mounting interface is essential to prevent unfiltered air bypass.
