The Iridium Spark Plug delivers exceptional durability and ignition performance.

  • Six times harder than platinum; withstands temperatures up to 4,000°F.
  • Because the iridium electrodes can be shrunk to only 0.4 mm, voltage requirements decrease while firing performance improves.
  • 360° laser welding of the 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.

Designed for reliable starts and smoother throttle response. 🔥
