NGK Laser Iridium Spark Plug Box of 4 (LMAR8AI-8)

The iridium-tipped center electrode on these NGK Laser Iridium spark plugs is six times harder than platinum, offering excellent durability and a stable spark. These are designed as direct OE replacements, meaning they meet the original equipment specifications for your vehicle. The pure alumina silicate ceramic insulator helps with heat transfer and provides superior strength, while the trivalent metal plating resists corrosion and seizing, making installation and removal easier down the road. A copper core is included to help with heat removal, and triple seals are used to prevent any leaks.

NGK Laser Iridium plugs are a solid option for vehicles that originally came with fine wire iridium alloy plugs. They feature a platinum pad on the ground electrode for even wear, which is especially beneficial in distributorless ignition systems. This box contains four spark plugs, suitable for many multi-cylinder engines. They are a well-made choice for maintaining reliable starts and consistent engine performance.
