Bosch Auto 9610 Bosch OE Fine Wire Double Iridium Spark Plug

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.
