ABOUT THIS PRODUCT

The Iridium TT Spark Plug combines the durability of an OE-style plug with the unmatched power and torque of high-performance engineering. Featuring the world's smallest 0.4mm Iridium Center Electrode, it maximizes firing potential while the 0.7mm Needle Tip Ground Electrode promotes higher spark energy and minimizes heat quenching. Built with DENSO's patented Iridium-Rhodium alloy formula, this spark plug boasts the highest concentration of Iridium for exceptional durability, enduring temperatures over 4000 Deg F and delivering over 100,000 miles of reliable performance. Its advanced Twin-Tip Technology, derived from Original Equipment Specification Super Ignition Plug design, pairs a fine wire Iridium Center Electrode with a Needle Tip Platinum Ground Electrode for superior ignition efficiency. The 360-degree laser welding process ensures a robust bond and structural integrity, while its premium materials and flat seat type enhance ignition and longevity. Enjoy improved fuel economy, lower emissions, and the confidence of a spark plug designed for ultimate endurance and power.
