NGK Laser Iridium spark plugs (box of 4, SILZKGR8E8S) use an iridium-tipped center electrode and a high-grade alumina ceramic insulator for OE-level ignition performance and longevity. Marketed for high ignitability and stable spark delivery, the plugs pair an iridium fine-wire tip with copper core construction and corrosion-resistant plating, intended as OE-equivalent replacements where iridium tip technology is specified.
