2. Product Description: Champion have developed the Gold Palladium spark plug featuring a fine wire center electrode for premium performance. The design features of this plug type allow a smaller gap to be run than with conventional electrodes, as the spark masking effect is considerably reduced, thus aiding easier starting and eliminating the misfire often associated with small spark gaps. The longer, slimmer core nose provides a greater shunt path distance to earth and also a greater cavity volume between the core nose and plug shell, allowing more efficient gas scavenging. Longer Service Life, Easier Starting, and Better protection against misfires.
