Bosch ZR5TPP33 Double Platinum Spark Plugs are engineered to extend performance life and durability. The fine wire design of the center electrode improves ignitability and performance in your engine while the Platinum tip on both the center and ground electrodes provide a 3X longer service life than standard Copper plugs. Nickel plated, rolled threads, combined with a factory preset gap, ensure simple, easy installation right out of the box - no anti-seize or gapping necessary.
