The NGK Racing spark plug is built for extreme motorsport use, offering specialized center electrode designs and a range of heat ratings to suit demanding engines. These plugs emphasize ignitability and durability under severe conditions, with trivalent metal plating for corrosion and seizing resistance, alumina-silicate ceramic for dielectric strength, and a copper core and triple seals to aid heat removal and prevent leakage.
