Using the same laser welding process as the Iridium Power spark plug, DENSO designed a long life spark plug factory-installed on luxury vehicles by automakers such as GM, Toyota, Honda and Mitsubishi. Using its patented Iridium alloy, DENSO was able to shrink the center electrode to 0. 7mm, dramatically improving ignitability and longevity.
- 100 percent pre-fired to ensure reliable operation
- Copper core center electrode for superior thermal conductivity
- Unique five-rib insulator reduces flashover and decreases voltage loss
- Dual copper and glass seal bonds the center electrode and insulator together for a gas-tight seal.
- Lasts up to three times as long as conventional plugs
