Bosch Auto 8122 Bosch OE Fine Wire Double Platinum Spark Plug

Platinum on the center electrode firing pin and laser welded platinum inlay ground electrode provide 3 times longer life than conventional 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.
