Iridium Spark Plug — engineered for long life and reliable ignition. ⚡️

Iridium is six times harder than platinum and withstands extreme temperatures up to 4,000°F, delivering durable performance even under severe conditions.

Because iridium electrodes can be shrunk to only 0.4 mm, voltage requirements decrease while firing performance improves, resulting in more consistent combustion.

360° laser welding of the electrode provides a durable seal that resists wear, and the tapered cut ground electrode with a U-groove forms a large-volume flame center for faster, more complete burn.
