Iridium Power
Iridium Power« plugs are for drivers that care about performance as well as drivers that care about mileage. These plugs best demonstrate their performance improvement during acceleration. The world's smallest center electrode (0.4mm) and specially shaped ground electrode delivers maximum spark energy while withstanding temperatures greater than 4000║ F. These features combine to achieve higher ignitability and require lower spark voltage than ever before. As a result, acceleration improves in comparison with normal plugs.

  • Tapered cut, U-Groove ground electrode
  • 0.4mm iridium center electrode
  • 360-degree laser welding assembly process

  • Required ignition voltage reduced
  • Unsurpassed center electrode durability
