NGK Laser Iridium Spark Plug Box of 4 (ILTR6S8)

These NGK Laser Iridium spark plugs are a solid option for keeping your engine running smoothly. They feature a fine wire center electrode made from an iridium alloy, which has a very high melting point and offers six times the durability of platinum. This means you get a consistent, stable spark for longer. The pure alumina silicate ceramic insulator helps with heat transfer and provides superior strength, while the copper core aids in heat removal from the plug itself. Plus, the trivalent metal plating helps prevent corrosion and seizing, making them easier to remove down the road. Most Laser Iridium plugs also include a platinum pad on the ground electrode for even wear, especially in modern distributorless ignition systems.

NGK designed these plugs to meet the demands of today's high-tech engines. The triple seals are there to prevent any leaks, ensuring reliable performance. If your vehicle originally came with fine wire iridium alloy plugs, these are a direct replacement designed to perform to the same high standards. They are sold in a box of four, so you'll have enough for most common V6 and V8 engine configurations.
