NGK 1989 Laser Iridium Spark Plug ILKR7B8 Fine Wire Iridium 12mm

The NGK 1989 Laser Iridium spark plug (ILKR7B8) is an OE-quality iridium spark plug built for long service life and dependable ignition. It has a laser-welded fine-wire iridium center electrode and a platinum pad on the ground electrode. This combination gives strong ignitability and a slow wear rate. It suits drivers who want a long-lasting replacement or a step up from a standard plug.

Key Features:

• Laser-welded iridium center electrode tip. Iridium is about six times harder than platinum, which helps durability and wear life.
• Platinum disc welded to the ground electrode for even wear, especially in distributorless ignition systems
• Pure alumina ceramic insulator and a 98% pure copper core for heat dissipation, conductivity and reliable starts
• Fine-wire center electrode design with a 0.6 mm tip
• Anti-corrosion and anti-seize plating for easier installation and removal
