Product Information

Premium Class Iridium Spark Plugs from Denso are fast becoming the standard for today's high-tech engines. Employing a revolutionary 360 degrees laser welding process, Denso has created a spark plug unlike anything on the market today. These innovative spark plugs are designed for durability under the most extreme conditions. Denso's patented Iridium alloy is 6 times harder and 8 times stronger than conventional platinum and can handle temperatures in excess of 4,000 degrees Fahrenheit.


  • Designed with heavy duty insulator that provides unparalleled dielectric strength and thermal conductivity under extreme temperatures
  • Five-rib design prevents flashover while decreasing voltage loss
  • Copper glass seal bonds the center electrode and insulator together for a gas-tight seal
  • Platinum center electrode utilizes platinum to shrink the surface area of the center electrode tip for maximum firing performance and minimum voltage requirements
  • Platinum ground electrode resists gas and electrical erosion and corrosion extending service intervals to 60,000 miles
