Product Details
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.
