NGK Laser Iridium Spark Plug Box of 4 (DILKAR8K8G)

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 is specifically chosen for today's high-tech engines, offering a great balance of performance and long life. They are built to meet the original equipment standards for your vehicle, ensuring a reliable replacement.

NGK uses a pure alumina silicate ceramic insulator for superior strength and better heat transfer, helping to prevent the plug from overheating. The pure copper core also aids in heat removal. For protection against corrosion and seizing, these plugs feature trivalent metal plating. The fine wire design of the center electrode ensures a consistently stable spark, which is important for efficient combustion. They also include a platinum fine wire tip on the ground electrode, which helps with even wear in modern ignition systems.

These spark plugs come as a set of four, ready to be installed. The triple seals are designed to prevent leakage, and the copper core helps dissipate heat effectively. They are a solid option if your vehicle originally came with OE DFE iridium alloy plugs.
