Spark plugs with fine wire center and/or ground electrodes operate better for two reasons. First, a smaller center electrode requires less voltage to jump the gap. This means fewer misfires, which will be seen in higher mileage and more horsepower. The second reason is smaller center and ground electrodes reduce quenching. Champion manufactures a variety of fine wire plugs for racing, powersport, small engine and automotive applications. |
