• REDUCE MISFIRES: The revolutionary 0.4 millimeter center electrode of the DENSO Iridium TT Spark Plug significantly improves combustion and reduces misfires to optimize power output like never before. The Iridium TT Twin-Tip Technology enables larger spark concentration and explosion, delivering more complete combustion, which translates to more superior fuel economy
• MAXIMIZE SERVICE LIFE: The unparalleled DENSO Iridium TT Spark Plug is tested to last well beyond 100,000 miles, with minimal loss to performance, contributing to more overall lifetime savings than any plugs available today. The DENSO Iridium TT design resists corrosion even in the harshest environments, and the state-of-the-art 360-degree laser welding technology enables a superior omnidirectional ignition rather than a flat ignition. This minimizes the quenching effect, giving your vehicle more power and better fuel economy

Power and Associates Chairman’s Award, and numerous supplier awards for quality from companies like Toyota, Lexus, General Motors, and Chrysler
