C7HSA SPARK PLUG (NGK)

This C7HSA SPARK PLUG (NGK) (86-4629)is a performance spark plug with a nickel electrode material that provides smooth, reliable starts. This is a Standard NGK nickel spark plug that features a specially designed v-groove center electrode, improving ignitability and reducing quenching. It has a 98% pure copper core superb conductor of electricity better than any other material used in spark plugs and transfers heat faster. The insulator material in the new plugs is nearly pure alumina doped with trace amounts of other oxides designed to increase high-temperature shunt resistance and reduce electrical current leakage through the ceramic.
