      Warranty Details (1 YR REPLACEMENT IF DEFECTIVE)

      The Denso Twin-Tip Technology was developed from Original Equipment Specification Super Ignition Plug (SIP) design, fusing a Fine Wire Iridium Center Electrode with a Needle Tip Platinum Ground Electrode. The DENSO Iridium TT combines the power and torque of a high performance plug with the endurance of a long life original equipment spark plug. So you can drive around the Earth over 4 times, with lower emissions and better fuel economy. That's over 100 thousand miles of uncompromised performance.

      Product Features:

      • 0.4mm Iridium Center Electrode: World's Smallest Diameter that maximizes firing potential
      • 0.7mm Needle Tip Ground Electrode: Promotes higher spark energy and less heat quenching
      • DENSO Patented Optimized Iridium-Rhodium Alloy Formula: Highest concentration of Iridium vs. competitors for greater durability
      • DENSO Patented 360 degree laser welding process: Ensuring exceptional quality and structural strength to the Iridium Center Electrode
