NGK Laser Platinum Spark Plug Box of 4 (PFR5R-11)

This is a box of four NGK Laser Platinum spark plugs, part number PFR5R-11. These are designed as direct OE replacements, meaning they match what your vehicle came with from the factory. They're built with a pure alumina silicate ceramic insulator for strength and heat transfer, and the trivalent metal plating helps prevent corrosion and seizing, making them easier to remove later on. The copper core inside helps dissipate heat, keeping the plug from overheating, and the triple seals are there to prevent any leaks.

What sets these apart is the dual platinum surface on both the center and ground electrodes. This design helps them wear down slowly and evenly, which is especially beneficial for vehicles with distributorless ignition systems. This slow wear rate contributes to a stable idle, better fuel efficiency, and lower emissions over their service life. They are recommended for vehicles that originally came with fine wire platinum alloy spark plugs.

This set fits a wide range of vehicles, including models like the Chrysler Crossfire, Mercedes-Benz C240, and Kia Optima. Always check the fitment guide to confirm compatibility with your specific car.
