The NGK Racing spark plug is crafted for extreme competition use and engineered to endure the harshest engine conditions. Special center-electrode geometries and insulator designs improve ignitability, durability and throttle response across varied heat ranges. Ceramic insulation and a copper core aid thermal management, corrugated ribs reduce flashover, and trivalent metal plating delivers corrosion and anti-seize protection to support repeated high-stress servicing.
