Denso Iridium TT Spark Plug

The Iridium TT Twin Tip Technology delivers far less obstruction to the spark allowing an omni-directional explosion. This minimizes the quenching effect and results in a more effective, more complete combustion. Better combustion means more power and better fuel economy, as fuel is burned more efficiently with each piston firing. The large center and ground electrodes seen on a Standard Plug increases quenching of the explosion, meaning the spark explosion is restricted by the electrodes above and below the gap, allowing it to spread to either side, but not grow with full range. Developed with DENSO's own optimized Iridium alloy; this is the smallest mass-produced center electrode available today. DENSO selected Iridium and engineered it with Rhodium to build the most durable alloy for spark plugs. The patented formula has the highest concentration of Iridium of any spark plug and outperforms in the most severe engine temperatures resisting oxidation and voltage wear for over 100,000 miles. Precision welding by DENSO's state-of-the-art 360-degree laser welding technology allows the Iridium TT's twin tips to deliver omni-directional ignition, contrary to the flat sandwich ignition offered by other spark plugs in the market. The superior ignition of the Iridium TT means each spark burns the fuel more efficiently, giving your vehicle more power and better fuel economy. To provide the best plug in the market, DENSO developed a proprietary 360-degree laser welding process : the result is the highest quality bond that ensures structural support for the Iridium center electrode, which resists wear and oxidation, even in the harshest combustion environments.
  • Utilizing decades of experience developing the world's leading spark plugs, the Iridium TT draws from the best features of the DENSO family of spark plugs, giving you more power in a more versatile plug.
  • Engineered with the smallest tip in the market, the DENSO Iridium TT spark plug delivers more complete combustion, giving you superior fuel economy over any other plug.
  • Unparalleled, the Iridium TT is designed to last beyond 100,000 miles providing coverage for most makes and models on the road today.
