NGK Laser Platinum Spark Plug Box of 4 (PFR7H-10)

The dual platinum surfaces on these NGK Laser Platinum spark plugs are laser welded to ensure a slow wear rate, which means they'll last longer and provide consistent performance. This design is a step up from standard nickel plugs, offering high ignitability for reliable starts and a more stable idle. They're built to meet OE specifications, so you can expect them to fit and function just like the original equipment on your vehicle.

Inside, a pure alumina silicate ceramic insulator helps manage heat effectively, preventing the plug from overheating. You'll also find a trivalent metal plating on the exterior, which helps resist corrosion and makes them easier to remove down the road. The copper core is there to help with heat removal, and triple seals are used to prevent any leaks. These are a solid choice if your vehicle originally came with fine wire platinum alloy plugs, offering improved fuel efficiency and lower emissions.
