• The spark plug is made of iridium gold and uses a new type of high alumina ceramic as an insulator. The insulator skirt is long and protrudes beyond the end face of the housing. This design gives the spark plug excellent heat absorption capacity and pollution resistance. At the same time, it can effectively use the intake air for cooling, and broaden its thermal adaptation range
