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.

Review: I don't know any more than that except that I needed to change mine and that the car runs great with these in it - I read on some Nissan forums that these plugs came in this Sentra from the factory.

Time will tell if they last as long as they should, but being a Japanese company that's an offshoot of Toyota Motors, Nippon Denso is known for high quality and I've read good things about their products.
