    FAQ

    A glow plug is a heating element used in diesel engines to assist with starting. Its function is to heat the air inside the combustion chamber before and during engine start, ensuring proper ignition of the fuel-air mixture, especially in cold conditions. This improves starting performance, reduces emissions, and ensures smoother engine operation.


    Key specifications include voltage (typically 4.4V–12V depending on system), thread size (such as M8, M10, or M12), overall length, heating element type (metal or ceramic), and connector type. Glow plugs must withstand extremely high temperatures (often exceeding 800–1000°C) and rapid heating cycles while maintaining durability and reliability.


    Replacement is necessary when the glow plug fails or loses efficiency. Common symptoms include difficult cold starts, rough idling after startup, increased smoke, or glow plug warning lights. It is often recommended to replace glow plugs in sets to maintain consistent performance.


    Porza offers a fit guarantee option where your vehicle details, such as license plate or VIN, are checked against product specifications. This ensures the glow plug matches the correct dimensions, voltage, and compatibility with your engine, reducing the risk of incorrect fitment.


    Porza supplies high-quality ignition and engine 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 reliable maintenance 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.
