Installation Notes and Tips

Verify the specified gap, thread diameter, reach, and seat type before installation. This plug is listed with a 0.044 in. pre-gap, but final installation should always follow the vehicle service specification. Use the correct torque procedure for the cylinder head material and inspect ignition components such as coils and boots when replacing plugs on higher-mileage vehicles.
