DENSO Double Platinum Spark Plugs
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 double platinum design provides reduced erosion and longer life while minimizing spark gap growth. Better performance and durability is found in Denso Double Platinum spark plugs.
