Six times harder than platinum, iridium doesn't melt in temperatures up to 4,000 Degrees F
Because the plug's iridium electrode can shrink to only 0.4mm, voltage requirements decrease while firing performance improves
360 Degrees 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
