    Ignition Coil

    The Ignition Coil (GN10494-12B1) provides the high voltage needed for strong and reliable ignition performance. Replacing a weak coil restores smooth acceleration, efficient combustion, and dependable engine operation. Use Porza’s smart search to find the correct coil.

    FAQ

    An ignition coil is an electrical component that transforms the low voltage from the vehicle’s battery into the high voltage required to create a spark at the spark plugs. Its function is to generate and deliver this high-voltage current at the correct timing, enabling ignition of the air-fuel mixture in petrol engines for proper combustion.

    Key specifications include operating voltage (typically 12V), output voltage (often up to 30–40 kV), coil design (single, double, or coil-on-plug), connector type, and mounting configuration. Ignition coils must withstand high temperatures (commonly -40°C to +150°C), vibration, and electrical stress while delivering consistent spark energy and precise timing.

    Replacement is necessary when the coil fails or becomes weak. Common symptoms include engine misfires, rough idling, reduced power, increased fuel consumption, difficulty starting, or a check engine light. Fault codes related to ignition or specific cylinders often indicate a failing ignition coil.

    Porza offers a fit guarantee option where your vehicle details, such as license plate or VIN, are checked against product specifications. This ensures the ignition coil matches your engine’s requirements, including electrical connections, mounting type, and performance characteristics.

    Porza supplies high-quality ignition 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 reliable 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.
