NGK Double Platinum Spark Plug Box of 4 (PZFR5F-11)

The pure copper core inside these NGK spark plugs helps pull heat away from the firing tip, preventing the plug from overheating and ensuring reliable starts. These are NGK Laser Platinum plugs, which means they have a platinum pad on the ground electrode, designed to handle the wear from distributorless ignition systems. This dual platinum setup helps them last longer and maintain a stable idle compared to standard nickel plugs.

NGK builds these plugs with a high-grade pure alumina ceramic insulator for strength and better heat transfer, and they add trivalent metal plating to the threads to resist corrosion and make them easier to thread in. The corrugated ribs on the insulator help prevent flashover, which is when the spark jumps to the side instead of across the gap. They also feature triple seals to prevent any leaks.

These are a good choice if your vehicle originally came with fine wire platinum alloy plugs. They are designed as an OE equivalent replacement, fitting a wide range of vehicles from Acura and Honda to Chrysler and Dodge, helping to improve fuel efficiency and lower emissions.
