NGK Laser Platinum Spark Plug PFR7Q - Set of 4 - Fits Select Audi and Porsche 2003-2006

Fits select 2003-2006 Audi RS6 and Porsche Cayenne (Turbo / Turbo S).

NGK Laser Platinum spark plugs are engineered to match original equipment specifications for high-performance European engines. These plugs utilize a fine-wire platinum tip and a platinum pad on the ground electrode to ensure consistent ignitability and a longer service life compared to standard nickel alternatives. This design is specifically optimized for distributorless ignition systems, providing stable idling, improved fuel efficiency, and superior anti-fouling characteristics.

Construction includes a high-grade alumina silicate ceramic insulator and a 98% pure copper core, which facilitates rapid heat removal to prevent overheating under load. The trivalent metal plating provides long-term resistance against corrosion and seizing, ensuring the plugs remain easy to remove at the end of their service interval.
