## 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.

Review: Awesome Spark Plugs - I’m very pleased with the plugs I bought at desertcart/AD Auto Parts. When I drove my vehicle I noticed the engine was running a lot smoother and I could feel more power on the engine. This only translates into one thing, Denso iridium long life spark plugs are much better quality than the competition. The price was worth it every penny and my delivery was right on time. Thank you
