The NGK Racing spark plug is engineered for extreme engine conditions and racing venues worldwide. Special electrode and insulator configurations improve ignitability, durability and throttle response across a wide range of heat ratings. High-grade ceramic insulation, corrugated ribs and a copper core help manage heat and prevent flashover, while trivalent plating provides anti-corrosion and anti-seize protection to simplify installation and removal under repeated service cycles.
