What design features make the Iridium Long Life stand out from competitors?

DENSO's ultimate long life spark plug comes factory installed on the latest high performance and luxury vehicles by automakers such as Toyota, Lexus, GM, Cadillac, Honda, Acura, and Mitsubishi. Using its patented Iridium alloy and patented 360° laser welding process, DENSO was able to shrink the center electrode to 0.7mm, dramatically improving ignitability and achieving the ultimate longevity -- longer than any other OE plug available.
