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, while maintaining the life of the plug.
The Titanium-enhanced alloy on the ground electrode also increases durability, which is critical to minimize tip erosion and achieve the new Twin-Tip design
Superior ignitability of the DENSO Platinum TT means more efficient combustion, which yields better engine performance in terms of power and fuel economy.

REDUCE EMISSIONS AND MISFIRES: The patented DENSO Spark Plug enables complete fuel ignition in the combustion chamber. It virtually eliminates erratic starts caused by poor fuel mixtures and excessive soot buildup. The DENSO Spark Plug employs a unique ground electrode designed to generate a larger spark nucleus at the point of ignition. Greater spark energy means improved flame travel, producing more complete, consistent, and efficient combustion
GAIN GREATER FUEL EFFICIENCY: This DENSO Spark Plug fires leaner mixtures than conventional plugs and improves throttle response. Its ground electrode was developed to improve ignitability for increased efficiency in emission gas purification and fuel consumption. The DENSO Spark Plug is 100 percent pre-fired to ensure reliable operation and lasts twice as long as conventional plugs. The unique five-rib insulator reduces flashover and decreases voltage loss
RELY ON QUALITY AUTO PARTS: From the development of direct ignition coils to revolutionizing the concept of the aftermarket performance spark plug by using platinum and iridium, DENSO is often on the front lines of product advancement
TRUST IN DENSO: The automotive industry has recognized the DENSO commitment to quality through such prestigious awards as the Deming Award for Quality, the J.D. Power and Associates Chairman's Award, and numerous supplier awards for quality
