DENSO Platinum TT

What features make the Platinum TT a superior spark plug?
DENSO’s revolutionary Twin-Tip design uses the latest OE technology in combination with Platinum and Titanium, two highly durable precious metals. The center electrode is created using an extremely durable Platinum alloy that allows for the reduction of the tip size to 1.1mm in diameter, to increase performance, while still maintaining plug life. The Titanium-enhanced alloy on the ground electrode further increases durability, which is critical to minimize tip erosion and allow the high-performing Twin-Tip design to function over the long-term. These design features combine to offer better performance through reduced quenching which results in a larger spark and faster flame propagation for a more complete combustion and maximized fuel efficiency.

What makes the Platinum TT stand out above the competition?
Superior ignitability of the DENSO Platinum TT means more efficient combustion, which yields better engine performance in terms of power and fuel economy. Better mileage, more power and faster starts, all while reducing carbon emissions are what places the Platinum TT Spark Plug heads above the competition.
