Denso Platinum TT Spark Plugs
Denso Platinum TT spark plugs originated from Denso's Twin-Tip design for original equipment use in the most technologically advanced automobiles. But now Denso offers this cutting-edge technology in a platinum/titanium design customized for today's value-minded automotive enthusiasts.
Denso pioneered the use of platinum in spark plug manufacturing. To maximize longevity and enhance durability, Denso applied platinum to both the center and ground electrodes.
