NGK Laser Iridium Spark Plug (LTR6DI-8)

When it's time to replace your spark plugs, especially on modern engines that demand a precise spark, NGK Laser Iridium plugs are a solid choice. These are designed as direct OE replacements, meaning they're built to the same high standards as the plugs your vehicle came with from the factory. They combine a fine wire iridium center electrode with a platinum pad on the ground electrode, a setup that ensures a stable spark and even wear over time, which is especially important for distributorless ignition systems.

The iridium center electrode is notably durable, offering significantly longer life compared to platinum. NGK also uses a pure alumina silicate ceramic insulator that's strong and helps manage heat effectively. For added protection against seizing and corrosion, these plugs feature a trivalent metal plating. This combination of materials and design helps prevent overheating and ensures reliable starting, making them a great option for a wide range of Ford and Lincoln vehicles like the Escape, Explorer, and Fusion.

You get a box of four plugs, which is what most common 4-cylinder and V6 engines will need. The copper core inside the insulator aids in heat removal, and triple seals are used to prevent any leaks. These are a well-built replacement for vehicles originally equipped with fine wire iridium alloy plugs.
