Product Details
The center electrode on these NGK Laser Iridium spark plugs is tipped with an iridium alloy, which has an extremely high melting point and is six times harder than platinum. This design helps ensure a stable spark and offers excellent durability, making them a solid choice for many modern engines. They are built to meet the original equipment specifications for vehicles that originally came with fine wire iridium plugs.
NGK uses a pure alumina silicate ceramic insulator for superior strength and better heat transfer, helping to prevent overheating. The copper core also aids in heat removal. For added protection, these plugs feature trivalent metal plating to resist corrosion and seizing, and triple seals are used to prevent any leakage. Many of these plugs also include a platinum pad on the ground electrode, which helps them wear evenly in distributorless ignition systems.
