CF240 MANN Filter Secondary Air Filter

This secondary air filter, manufactured by MANN Filter, plays a crucial role in maintaining engine health. Part number CF240 effectively removes contaminants from the air before it reaches the engine, commonly found within vehicle air intake systems. By delivering clean air, this filter contributes to improved fuel efficiency and reduced emissions. It’s built to exacting standards in Germany and has dimensions of 310 x 70 x 70 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.
