NGK Laser Iridium Long Life Stock Heat Spark Plug

You're getting a box of four NGK Laser Iridium spark plugs, part number 6481. These are designed as direct replacements for your vehicle's original plugs, offering a solid combination of performance and long life. The fine wire center electrode, made with an iridium alloy that has a very high melting point, ensures a consistent spark and durability. This makes them a good choice for today's modern engines.

NGK builds these plugs with a pure alumina silicate ceramic insulator, which helps with strength and heat transfer. They also feature trivalent metal plating to resist corrosion and seizing, making them easier to remove later. The pure copper core inside helps dissipate heat, preventing the plug from overheating, and the triple seals are there to prevent any leaks. Many of these plugs also include a platinum pad on the ground electrode for even wear, especially in distributorless ignition systems.

These NGK Laser Iridium plugs are a popular choice for many vehicles, including models like the Land Rover LR2, Subaru Forester, and Volvo C30. They are intended to provide reliable starts and a stable spark over a long service life.
