NGK Laser Iridium Spark Plug Box of 4 (ILKAR8H6)

This product includes a box of four NGK Laser Iridium spark plugs, part number ILKAR8H6. These are designed as a direct replacement for your vehicle's original spark plugs, ensuring a proper fit and function. They feature an iridium-tipped center electrode, which is significantly harder than platinum, offering excellent durability and a stable spark over time. The pure alumina ceramic insulator helps manage heat effectively, while the copper core aids in removing excess heat from the plug itself. For vehicles with distributorless ignition systems, a platinum pad on the ground electrode helps ensure even wear.

The iridium alloy used in these plugs has a very high melting point, making them well-suited for modern, high-performance engines. NGK also applies a trivalent metal plating to the exterior of the spark plug, which helps prevent corrosion and makes them easier to remove later on. These plugs are a solid option if your vehicle originally came with fine wire iridium alloy plugs from the factory.
