NGK Laser Iridium/Platinum Spark Plug (ILTR6E11)

When it’s time to replace your spark plugs, especially if your vehicle originally came with fine wire iridium or platinum plugs, NGK Laser Iridium plugs are a solid choice. These are designed to be a direct OE replacement, meaning they’re built to the same standards as the plugs your car came with from the factory. They help ensure your engine runs smoothly and efficiently, providing reliable starts and consistent power delivery.

What sets these plugs apart is the combination of materials. The center electrode uses an iridium alloy, which has a very high melting point and is significantly harder than platinum, offering excellent durability and a stable spark. For even wear, especially in modern ignition systems, the ground electrode features a platinum pad. The pure alumina silicate ceramic insulator helps manage heat effectively, and the trivalent metal plating on the plug body resists corrosion and makes installation easier by preventing seizing.

This box includes four spark plugs, which is the correct quantity for most 4-cylinder engines. They are built to handle the demands of today's engines and are a popular choice for many vehicles, including models like the Buick Enclave, Cadillac CTS, and Ford F-150.
