OE Fine Wire design with Platinum firing pin on the center electrode requires up to 24% less voltage to ignite and up to 2 times longer life compared to standard copper spark plugs. 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. Bosch OE Fine Wire Platinum Spark Plugs deliver improved ignitability and fuel efficiency. The fine wire design with a platinum firing pin on the center electrode and tapered ground electrode are an economical upgrade from conventional copper core spark plugs. Engineered to meet or exceed Original Equipment specifications for platinum spark plugs.
