The NGK Racing spark plug is engineered for extreme use and demanding race conditions. Special center electrode configurations and insulator nose designs increase ignitability and durability across a range of heat ratings. NGK builds these plugs to withstand harsh engine environments, combining high-grade ceramic insulation, copper cores for heat removal, corrugated ribs to prevent flashover, and trivalent plating to resist corrosion.
