Denso Double Platinum Spark Plugs

Denso was the pioneer in introducing platinum spark plugs to the automotive aftermarket, but has hardly been content to rest on that achievement. Conventional platinum plugs use platinum for only the center electrode, while Denso Double Platinum spark plugs feature platinum on both the center and ground electrodes. This precious metal fights corrosion and erosion, ensuring superior spark performance and maximum spark plug life. Order the model recommended for your vehicle application.
