NGK Laser Platinum Spark Plug Box of 4 (PZFR6H)

The dual platinum surfaces on these NGK Laser Platinum spark plugs are laser-welded to the electrodes, which helps them wear slowly. This design is a big reason why they offer a longer service life compared to standard nickel plugs, and it contributes to stable idling and improved fuel efficiency. They are built as direct OE replacements, meaning they are made to fit and function just like the original plugs in a wide range of vehicles, including models like the Polaris Genesis I and TigerShark TS1100LI.

Inside, a pure alumina silicate ceramic insulator handles heat transfer effectively and provides solid strength, while the 98% pure copper core helps prevent overheating. For added protection, the trivalent metal plating resists corrosion and makes removal easier, preventing seizing. These plugs are a solid option if your vehicle originally came with fine wire platinum alloy plugs, ensuring you get reliable starts and consistent performance.
