    Fuel Filter

    The Fuel Filter (S 4391 NR) removes contaminants from fuel to protect injectors and ensure smooth engine operation. Replacing a clogged filter restores performance and fuel efficiency. Use Porza’s smart search to find the correct filter.



    FAQ

    A fuel filter is a component in the fuel system that removes dirt, rust, and other contaminants from the fuel before it reaches the engine. Its function is to ensure clean fuel delivery, protecting injectors and other sensitive components while maintaining efficient combustion and engine performance.


    Key specifications include filtration efficiency (micron rating), flow rate capacity, filter dimensions, and compatibility with petrol or diesel systems. Fuel filters are typically made with high-efficiency paper or synthetic media designed to trap fine particles while allowing sufficient fuel flow. They must withstand fuel pressure and temperatures commonly ranging from -30°C to +120°C.


    Replacement is necessary at regular service intervals or when signs such as reduced engine performance, difficulty starting, or fuel system contamination occur. A clogged fuel filter can restrict fuel flow and lead to poor engine operation or damage to fuel system components.


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


    Porza supplies high-quality fuel system 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.
