1923-IXU22 DENSO IRIDIUM SPARK PLUG 99-17 TWIN CAM 86-18 XL IXU22

Six times harder than platinum, iridium doesn't melt in temperatures up to 2204°C (4.000°F)
Because the iridium electrodes of these plugs can be shrunk to only 0,4 mm, voltage requirements decrease while firing performance improves
360° 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
