MANN air filters

The air filter C21138/1 is an essential component in the air intake system of engines, designed to remove contaminants from the incoming air. It prevents dust, dirt, and other particulate matter from entering the engine, where they could cause wear and tear on internal components. The filter element is typically made of a porous material such as paper, foam, or cotton, which allows air to pass through while trapping particles. Paper filters are common in standard automotive applications due to their cost-effectiveness and sufficient filtration for typical driving conditions. Foam filters are more durable and can be washed and reused, making them suitable for dusty environments. Cotton filters offer high airflow and excellent filtration, often used in performance applications. The air filter housing is designed to protect the filter element and ensure proper sealing, preventing unfiltered air from bypassing the filter. Regular maintenance and replacement of the air filter are crucial for maintaining engine performance, fuel efficiency, and reducing emissions.
