NGK Laser Platinum Spark Plug Box of 4 (PFR8S8EG) for Select Audi, Porsche, and VW 2009-2019

Fits select 2009-2019 Audi A6, A7, A8, Q5, Q7, S4, S5, and SQ5, Porsche Cayenne and Panamera, and Volkswagen Touareg models.

NGK Laser Platinum spark plugs are engineered as high-performance OE replacements to provide superior ignitability and a longer service life than standard nickel plugs. Featuring laser-welded platinum surfaces on the center electrode and most ground electrodes, these plugs ensure minimal gap erosion and stable idling throughout their lifespan. The pure alumina silicate ceramic insulator provides exceptional dielectric strength, while the trivalent metal plating protects the shell from corrosion and seizing in the cylinder head, even in high-heat environments.

• OE Specific Design: Engineered to meet original equipment requirements for fit, heat range, and durability.
• Platinum-to-Platinum Surfaces: Laser-welded platinum pads provide even wear and consistent performance in distributorless ignition systems.
• Thermal Management: 98% pure copper core facilitates rapid heat removal to prevent pre-ignition and overheating.
• Anti-Fouling Performance: Fine-wire design improves fuel efficiency and reduces emissions while preventing carbon buildup.
• Flashover Prevention: Corrugated ribs on the insulator prevent electrical leakage (flashover) for reliable starts in all conditions.
