NGK Laser Iridium Spark Plug Box of 4 (ILTR6M9G)

The fine wire center electrode on these NGK Laser Iridium spark plugs is made from an iridium alloy, which has an extremely high melting point. This makes them a solid choice for today's modern, high-performance engines, offering both durability and a consistently stable spark. These plugs are designed as direct OE replacements, meaning they fit right and perform as the original equipment manufacturer intended for a wide range of vehicles.

NGK uses a pure alumina silicate ceramic insulator for superior strength and better heat transfer, helping to prevent overheating. The center electrode is tipped with iridium, a material six times harder than platinum, ensuring long-lasting performance. For even wear in distributorless ignition systems, most of these plugs also feature a platinum pad on the ground electrode. Plus, the trivalent metal plating helps prevent corrosion and seizing, making installation and removal easier down the road.

This box contains four spark plugs, enough for most 4-cylinder engines. They are a popular choice for vehicles originally equipped with fine wire iridium plugs, offering a reliable way to maintain your engine's ignition system. If your vehicle uses this type of plug, you can expect improved starting and a stable idle.
