NGK Laser Platinum Spark Plug Box of 4 (FR5AP-10)

NGK is well-known for making reliable ignition components, and their Laser Platinum spark plugs are a prime example of that. If you're looking to replace the spark plugs in your vehicle, these are built to OE specifications, meaning they're designed to perform just like the ones that came from the factory. They're a solid choice for vehicles that originally came with fine wire platinum alloy plugs, ensuring a direct fit and proper function.

These plugs use a laser-welded dual platinum surface, which helps them wear slowly and consistently. This translates to stable idling, better resistance to fouling, and can even contribute to improved fuel efficiency and lower emissions. The insulator is made from pure alumina silicate ceramic, which is strong and transfers heat well, while the copper core helps manage heat buildup. Plus, the trivalent metal plating on the threads makes them resistant to corrosion and seizing, which is always a plus when you're working on your car.

This set comes with four spark plugs, enough for most 4-cylinder engines. They feature triple seals to prevent any leaks and corrugated ribs on the insulator to prevent flashover. You'll find these are a popular choice for many Infiniti and Nissan models, including the Pathfinder, Xterra, and Altima.
