NGK Laser Iridium Spark Plug (SILZKFR8F7S)

These NGK Laser Iridium spark plugs are built for vehicles that originally came with iridium alloy plugs. They offer a great combination of performance and how long they last. The center electrode is made from an iridium alloy, which is much harder than platinum and helps ensure a consistent spark over time. NGK uses a pure alumina ceramic insulator that's strong and helps transfer heat away from the plug, keeping it from overheating. The ground electrode has a platinum pad to help it wear evenly, especially in modern ignition systems, and that helps maintain a stable spark.

The fine wire design of the center electrode is key to its durability and consistent spark delivery. Iridium has a very high melting point, making it a good choice for today's high-tech engines. Plus, the trivalent metal plating on the threads helps prevent corrosion and makes them easier to install without seizing. These plugs are designed to be a direct replacement for your original equipment, meaning they fit right and work as intended.
