NGK Laser Iridium Spark Plug (DILKAR7Q8)

NGK is well-known for making reliable ignition components, and their Laser Iridium spark plugs are a prime example of that. These plugs are built to meet the demands of modern engines, offering a great balance between performance and how long they last. They use an iridium-tipped center electrode, which is a very hard material that helps ensure a consistent spark over time.

What makes these plugs stand out is the combination of materials. The pure alumina silicate ceramic insulator helps manage heat effectively, while the 98 percent pure copper core also aids in removing heat from the plug. For added protection against corrosion and seizing, they feature a trivalent metal plating. You'll also find a platinum pad on the ground electrode, which helps with even wear, especially in distributorless ignition systems, and contributes to a more stable spark.

These are a solid option if your vehicle originally came with iridium alloy spark plugs. The triple seals are designed to prevent leaks, and the fine wire center electrode is key to maintaining that stable spark for optimal engine performance.
