With a copper core for enhanced thermal conductivity and a unique five-rib insulator to reduce voltage loss, these plugs last up to three times longer than conventional models. Trusted by luxury automakers, they deliver reliable, high-performance ignition tailored for cars and trucks. ## Description 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.
