NGK Laser Iridium High Ignitability spark plugs (box of 4) use a fine iridium center electrode for consistent spark and long life, with an iridium tip far harder than platinum. Built for OE replacement and high-tech engines, they feature a pure alumina ceramic insulator, a 98% pure copper core for heat removal, and raised platinum or fine-wire ground electrodes for even wear in distributorless ignitions. Recommended for OE-style applications.
