NGK Multi-Ground Spark Plug Box of 4 (PFR6W-TG)

NGK is well-known for making reliable ignition components, and their Laser Platinum spark plugs are a prime example of that. This particular plug, the PFR6W-TG, is designed to give you high ignitability and a longer service life than typical nickel spark plugs. It's built to meet specific manufacturer ignition requirements and is a solid choice for a wide range of vehicles, including models like the Audi A6 Quattro, Volkswagen Touareg, and Audi S5.

What sets these plugs apart is the multi-ground electrode design, which helps improve ignition capabilities and makes them less sensitive to the increased voltage needs that can come with gap growth over time. The pure alumina silicate ceramic insulator offers superior strength and helps with heat transfer, while the 98% pure copper core aids in removing heat to prevent overheating. You'll also find triple seals to prevent leaks and corrugated ribs on the insulator to prevent flashover, all contributing to stable idling and improved fuel efficiency.
