Denso Iridium Spark Plug

Six times harder than platinum, iridium doesn’t melt in temperatures up to 4,000 degrees Fahrenheit

Because the iridium electrodes of these plugs can be shrunk to only 0.4mm, voltage requirements decrease while firing performance improves

360 degree laser welding of electrode provides a seal that resists wear even in the worst conditions

Ground electrode features a tapered cut and u-groove that form a large volume area for the flame’s center
