NGK Laser Iridium Spark Plug Box of 4 (ILTR6R8G)

When it's time to replace your spark plugs, especially in a modern engine that relies on a precise spark for optimal performance and fuel efficiency, NGK Laser Iridium plugs are a solid choice. These are actual OE or equivalent replacements, meaning they're built to the same standards as what came on your vehicle from the factory.

The center electrode on these plugs uses an iridium alloy, which has a very high melting point and is six times harder than platinum. This durability means a more consistent spark over a longer period, which is crucial for today's high-tech engines. The pure alumina silicate ceramic insulator helps with heat transfer, and the trivalent metal plating on the threads helps prevent corrosion and seizing, making them easier to remove next time. Most of these also feature a platinum pad on the ground electrode for even wear, especially in distributorless ignition systems.

This box contains four spark plugs, which is what you'll need for most 4-cylinder engines. They fit a range of Ford and Lincoln vehicles, including models like the Ford F-150, Ford Edge, and Lincoln Navigator. The copper core also aids in heat removal, helping to prevent the plug from overheating.
