Set of 4 Pcs Iridium Spark Plugs NGK 94862 Laser Iridium Spark Plug LTR7CP13 for Ford F-150 Mustang F-250 F-350 E-350 E-450

Professional Grade Set for Complete Replacement

The original set of four iridium spark plugs NGK Laser Iridium series (part number 94862, marking LTR7CP13) is designed for full servicing of cylinders in Ford and Lincoln gasoline engines. Purchasing a ready-made set of 4 pieces eliminates performance variance between cylinders, ensures uniform electrical circuit resistance, and guarantees equal wear across ignition system components. The items are supplied in individual factory packaging combined inside an official branded box.

Laser Iridium Series Engineering and Operational Lifespan

Each spark plug in the set features an ultra-fine center electrode with an iridium tip welded using precision laser welding technology. This reduces electrical voltage requirement, ensures instant ignition of the fuel-air mixture, and promotes efficient fuel combustion. The ground electrode is equipped with a platinum pad to prevent burn-off from the electric arc, maintaining a stable 1.3 mm spark gap throughout its entire service interval. The shell features trivalent chromium plating to prevent thread seizure in the aluminum cylinder head and protect against corrosion.
