DENSO PREMIUM CLASS IRIDIUM SPARK PLUG

Denso's Premium Class Iridium Spark Plugs is 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. 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.

Specification:
  • 12 mm thread size
  • 19 mm reach
  • 0.68 in. hex size
  • 0.03 in. gap size
  • Gasket seat style
  • Resistor plug type
  • Tapered cut U-groove ground electrode
  • Removable terminal
  • Heat range 24

Features:
  • 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
