NGK Multi-Ground Spark Plug Box of 4 (PPFR6T-10G)

The pure alumina silicate ceramic insulator in these NGK spark plugs offers superior strength and better heat transfer, helping to prevent overheating. These are Laser Platinum plugs, designed to give you high ignitability and a longer service life than standard nickel plugs. They are built to meet specific manufacturer ignition requirements, making them a solid choice for vehicles originally equipped with OE fine wire platinum alloy plugs.

What really sets these apart is the multi-ground electrode design. This feature improves ignition capabilities and makes them less sensitive to the increased voltage needed as the gap grows over time. Most of these plugs also have a platinum pad on the ground electrode, which helps ensure even wear, especially in distributorless ignition systems. You can expect stable idling, better resistance to fouling, improved fuel efficiency, and lower emissions with these NGK plugs.

This box contains four NGK PPFR6T-10G spark plugs, part number 5542. They are designed to fit a wide range of vehicles, including models like the Dodge Dakota, Jeep Grand Cherokee, and Saab 9-3. The triple seals are there to prevent leaks, and the corrugated ribs on the insulator help prevent flashover, ensuring a reliable spark.
