    Secondary Air Filter

    The Secondary Air Filter (AF1840) provides additional filtration to protect the engine in high dust environments. Replacing the secondary filter ensures optimal airflow and long engine life. Use Porza’s smart search to find the correct filter.

    FAQ

    A secondary air filter is an additional filtration component installed alongside the primary air filter in the intake system. Its function is to provide an extra layer of protection by capturing finer particles that may pass through the main filter. This helps ensure cleaner air reaches the engine, improving durability and maintaining optimal performance, especially in demanding or dusty environments.


    Key specifications include filtration efficiency (often higher than the primary filter), airflow capacity, dimensions, and filter material (typically fine paper or synthetic media). The filter must balance fine particle capture with sufficient airflow, and it should withstand operating temperatures typically ranging from 80–120°C in engine environments. Proper fitment within the air filter housing is essential for effective sealing.


    Replacement is necessary when the filter becomes clogged or reaches its service interval. Since it captures finer particles, it may clog faster than the primary filter in harsh conditions. Regular inspection is important, especially in off-road or heavy-duty applications where air contamination is higher.


    Porza offers a fit guarantee option where your vehicle details, such as license plate or VIN, are checked against product specifications. This ensures the secondary air filter matches the correct size and configuration for your intake system, 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 parts for both professional workshops and individual users.


    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 reliable and risk-free purchasing experience.
