• Six times harder than platinum, iridium doesn’t melt in temperatures up to 4,F
• Because the plug’s iridium electrode can shrink to only .4mm, voltage requirements decrease while firing performance improves
• 36 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
