Denso Spark Plugs - U Groove Platinum and Iridium Plugs - DENSOs Iridium Long Life plug is fast becoming the standard for todays high-tech engines. The properties of DENSOs patented Iridium alloy have broken through the spark plug technology barrier. Employing a revolutionary new 360 laser welding process, DENSO has created a spark plug unlike anything on the market today. Designed for durability under the most extreme conditions, DENSOs patented Iridium alloy is six times harder and eight times stronger than conventional platinum and can handle temperatures in excess of 4,000F. DENSO pioneered the use of platinum in spark plug manufacturing. To maximize the longevity and enhance the durability of the spark plug, DENSO applied platinum to both the center and ground electrodes. Platinum offers superior resistance to erosion and corrosion enabling DENSO to create a spark plug capable of consistent, extended operation in excess of 60,000 miles. DENSOs patented U-Groove spark plug enables complete combustion by allowing the spark to fill the gap created by the U shape. The ball of fire created in the U-Groove develops a larger and hotter flash front that virtually eliminates excessive fouling and erratic starts caused by poor fuel mixtures.
