NGK Laser Iridium Spark Plug Box of 4 (DILZKAR7D11S)

NGK Laser Iridium spark plugs are built for vehicles that originally came with OE iridium alloy plugs. They offer a solid combination of performance and long life, making them a great choice for keeping your engine running smoothly. The fine wire center electrode is made from an iridium alloy, which has a very high melting point, helping it stand up to the demands of modern engines and ensuring a stable spark every time.

These plugs feature a pure alumina silicate ceramic insulator that helps with heat transfer, keeping the plug from overheating. For added protection against corrosion and seizing, they have a trivalent metal plating. The ground electrode has a raised platinum pad, which helps it wear evenly over time, especially in distributorless ignition systems, and contributes to a more consistent spark. A pure copper core is also included to help with heat removal.

This set comes with four spark plugs, enough for most 4-cylinder engines. They are designed as a direct replacement for your original equipment plugs, so they should fit right in. Just remember to check your vehicle's specific needs to ensure these are the correct plugs for your application.
