NGK Laser Iridium Spark Plug Box of 4 (IFR6F8DN)

NGK is well-known for making reliable ignition components, and their Laser Iridium spark plugs are a prime example of that. These plugs are built to meet the demanding needs of modern engines, offering a solid balance between performance and how long they last. They are designed as an OE equivalent, meaning they are made to the same high standards as what originally came on your vehicle.

The center electrode uses an iridium alloy, which is significantly harder than platinum and can withstand high temperatures, making it ideal for today's advanced engines. This fine wire design helps ensure a stable spark every time. The insulator is made from pure alumina silicate ceramic, which is strong and helps transfer heat away from the plug. For added protection, the metal plating helps prevent corrosion and seizing, making them easier to remove later. Most of these plugs also have a platinum pad on the ground electrode to help them wear evenly, especially in distributorless ignition systems.

This set comes with four spark plugs, which is what most vehicles need for a complete tune-up. The copper core inside helps manage heat, and triple seals are used to prevent any leaks.
