Corrugated Ribs help prevent "Flashover" of spark which can lead to harmful misfires and rob you of performance.
Alumina Silicate insulator ensures dielectric strength and incredible physical strength.
Triple Gasket sealing process
Solid Copper Core - Other manufacturers claim to use a solid copper core, but NGK uses a large amount of copper to ensure greater spark and heat transfer.
Longer insulator nose - This superior design, sometimes called a "Power Tip" helps prevent loading up or fouling, even after prolonged periods of idling, or at slow speeds.
Double Dipped Zinc Chromate shell - tough, corrosion resistant zinc chromate coating, ensuring maximum rust resistance.
Note: Anti-Sieze should NOT be used on NGK Spark plugs in outdoor power equipment applications
