NGK Laser Iridium OE replacement Spark Plug Box of 4 (ILTR6A-8G)

The center electrode on these NGK Laser Iridium spark plugs is tipped with an iridium alloy, which has an extremely high melting point and is six times harder than platinum. This makes them a durable choice for your vehicle's ignition system. They are built to meet the original equipment specifications for your car, ensuring a direct replacement that works as intended.

NGK uses a pure alumina silicate ceramic insulator for superior strength and better heat transfer, helping to prevent the plug from overheating. The copper core also aids in heat removal. For vehicles with distributorless ignition systems, most of these plugs also feature a platinum pad on the ground electrode for even wear, contributing to a consistently stable spark. The trivalent metal plating helps resist corrosion and seizing, making them easier to remove later on.

This set includes four spark plugs, which is the correct number for many 4-cylinder engines. They are designed to be a straightforward replacement for your existing spark plugs, often requiring no special tools beyond what you'd typically use for a tune-up.
