The DENSO Double-Platinum plug features platinum on both the center and ground electrodes. The precious metal fights corrosion and erosion, ensuring superior spark performance and maximum spark plug life. DENSO Double Platinum spark plugs incorporate the precious metal on both the center and ground electrodes, not just on the center electrode as with conventional platinum plugs. The result is a significant improvement in spark plug life. Product Features:Platinum center electrodePlatinum ground electrodePremium shell construction with machine-rolled threadsSustained spark performance over 60,000 milesReduced secondary required voltage, increased ignition efficiency DENSO engineering studies show that Double Platinum plugs can run longer with reduced erosion, minimizing spark gap growth throughout the life of the plug.
