NGK Spark Plug is designed to withstand severe mechanical and thermal shock associated with high-revving, high-compression race engines. Fine-wire center and ground electrodes provide better sparking and enhanced ignitability. Zinc dipped shell prevents corrosion while the triple gasket seal eliminates combustion gas leakage. Special configurations are used for the insulator noses to improve throttle response and prevent fouling with corrugated ribs on insulator to prevent flashover.
