NGK Laser Iridium Spark Plug Box of 4 (DILZKR7B11GS)

The iridium alloy center electrode in these NGK Laser Iridium spark plugs has an extremely high melting point, making it six times harder than platinum. This design is specifically chosen for modern engines that demand reliable ignition. These plugs are built to meet the original equipment specifications for your vehicle, ensuring they perform as intended right out of the box.

NGK uses a pure alumina silicate ceramic insulator, which offers superior strength and helps transfer heat away from the plug's tip. This prevents overheating and contributes to reliable starting, even in tough conditions. The trivalent metal plating on the threads helps prevent corrosion and seizing, making them easier to remove during future maintenance. A fine wire center electrode ensures a stable spark, which is crucial for efficient combustion and consistent engine performance, especially in distributorless ignition systems.

These spark plugs come as a set of four, ready to replace the plugs in your Accord. The copper core also aids in heat removal, further contributing to the plug's longevity and performance. NGK's triple seals are designed to prevent any gas leakage, ensuring optimal combustion pressure is maintained.
