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
