• DENSO is 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 the DENSO Double Platinum plug features platinum on both the center and ground electrodes. This precious metal fights corrosion and erosion, ensuring superior spark performance and maximum spark plug life capable of extended operation in excess of 60,000 miles.
