The modern Champion Spark Plug embodies a number of technical improvements over the Spark Plugs of yesteryear, including advances in ceramic material, insulator and firing end design, plus copper cored centre electrodes giving a wider operating range, greater resistance to 'tracking' and they dissipate heat from the firing end faster. Replaces Champion No L10.
