OE Fine Wire Double Iridium
Bosch OE Fine Wire Double Iridium. All iridium plugs are NOT created equal. The ultra fine wire design and laser welded, tapered ground electrode deliver the ultimate in ignitability and high performance. The iridium-alloy center electrode firing pin and laser welded ground electrode with iridium alloy inlay help it to go the distance.

Features & Benefits:
  • Double Iridium electrodes - iridium firing pin and iridium ground electrode inlay offer higher performance and 4 times longer life compared to standard copper spark plugs
  • OE Fine Wire design requires up to 24% less voltage to ignite
  • 360 degree continuous laser welding increases durability for increased life
  • Copper core provides broader heat range to resist pre-ignition and fouling
  • Pre-gapped and nickel plated threads allow for quick installation without adjusting the gap or applying anti-seize
  • Tapered ground electrode allows for better ignition throughout the life of the spark plug
