BRAKE BLEEDER/FLUID EVAC.

Bosch Double Platinum Spark Plugs are engineered for up to 3X longer service life than conventional copper spark plugs. They feature platinum on the center electrode firing pin and a laser-welded platinum inlay ground electrode. The OE Fine Wire design requires up to 24% less voltage to ignite. A 360-degree continuous laser welding increases durability. The copper core provides a broader heat range to resist pre-ignition and fouling. These spark plugs are pre-gapped and have nickel-plated threads, allowing for quick installation without adjusting the gap or applying anti-seize. They are backed by a 5-year customer satisfaction guarantee and a 1-year technician warranty.
