    Air Filter

    The Air Filter (C 21 116/1) protects the engine by delivering clean, unrestricted airflow for optimal performance. Replacing a dirty filter improves fuel efficiency and ensures long engine life. Use Porza’s smart search to find the correct filter.



    FAQ

    An air filter is a component in the engine intake system that removes dust, dirt, and other contaminants from incoming air before it enters the engine. Its function is to ensure clean airflow, which is essential for efficient combustion, engine performance, and protection of internal components from wear and damage.


    Key specifications include filtration efficiency, airflow capacity, filter dimensions, and material type (paper, foam, or synthetic). The filter must balance effective particle removal with sufficient airflow. It should also withstand engine bay temperatures typically ranging from 80–120°C and maintain structural integrity under varying airflow conditions.


    Replacement is necessary when the filter becomes clogged, dirty, or reaches its recommended service interval. A restricted air filter can reduce engine performance, increase fuel consumption, and lead to higher emissions. Replacement frequency depends on driving conditions, with more frequent changes required in dusty environments.


    Porza offers a fit guarantee option where your vehicle details, such as license plate or VIN, are checked against product specifications. This ensures the air filter matches the correct size, shape, and performance requirements for your engine, reducing the risk of incorrect fitment.


    Porza supplies high-quality filtration components with fast delivery across Europe. Customers can order online or choose in-store pickup in the Netherlands, Germany, or Belgium. This allows quick and flexible access to essential maintenance parts for both professional workshops and individual users, with reliable European-wide shipping.


    If you select the fit guarantee, Porza verifies compatibility before shipment. If the product does not fit or meet expectations, it can be returned according to the return policy. This ensures a secure and risk-free purchasing experience.
