NGK Laser Platinum Spark Plug Box of 4 (PFR6G-13E)

NGK is well-known for making reliable ignition components, and their Laser Platinum spark plugs are a solid choice for your Jaguar XJR. These plugs are designed to be a direct replacement for your original equipment, meaning they'll fit right in and perform as expected. They help ensure your engine starts reliably and runs smoothly.

Compared to standard nickel spark plugs, the Laser Platinum design uses a platinum pad on the ground electrode, which helps them wear more slowly. This slow wear rate contributes to a stable idle and can help improve fuel efficiency and lower emissions. The pure alumina ceramic insulator is strong and helps manage heat, while the copper core also aids in removing excess heat from the plug. Plus, the trivalent metal plating on the threads helps prevent corrosion and makes them easier to remove next time.

These are recommended for vehicles that originally came with fine wire platinum alloy plugs, like your XJR. You'll get a box of four, which is exactly what you need for your V8 engine.
