£10
£50.76
The Champion RN79G / CCH530 is an industrial spark plug with a Gold Palladium fine wire centre electrode. Its design allows a smaller gap than conventional electrodes, reducing the spark masking effect. The longer, slimmer core nose provides a greater shunt path distance to earth and more cavity volume between the core nose and plug shell, allowing more efficient gas scavenging. It replaces 642 Champion.
