NGK Laser Iridium/Platinum Spark Plug Box of 4 (ILTR5A-13)

The center electrode on these NGK spark plugs features an iridium alloy tip, which has an extremely high melting point and is six times harder than platinum. This design helps ensure a consistently stable spark and offers improved durability for today's engines. These are actual OE or equivalent replacement spark plugs, meaning they meet the same standards as what came on your vehicle from the factory.

NGK builds these plugs with a pure alumina silicate ceramic insulator that offers superior strength and better heat transfer, helping to prevent overheating. The pure copper core also aids in heat removal, and the trivalent metal plating on the exterior provides good resistance to corrosion and seizing. Most of these plugs also include a platinum pad on the ground electrode for even wear, which is especially beneficial in distributorless ignition systems. They come as a box of four, ready to replace the plugs on a wide range of Ford, Lincoln, and Mercury vehicles, including models like the Ford Fusion, Lincoln MKZ, and Mercury Milan.

For best results, these are recommended for vehicles that originally came with OE fine wire iridium alloy plugs. The triple seals are designed to prevent leakage, ensuring reliable performance.
