• NGK Standard line spark plug in NGK's yellow box packaging
• Nickel alloy center electrode for consistent performance
• Solid 98% pure copper core for heat dissipation, conductivity and ultra wide heat ranges
• High grade alumina silicate ceramic insulator, with triple gasket sealing against combustion gas leakage
• Trivalent metal plating resists corrosion and seizing; cold-rolled threads help prevent cross-threading
