The NGK Laser Iridium spark plug blends longevity and solid ignitability using an iridium-tipped center electrode that withstands wear far better than traditional materials. Engineered for OE-type applications, these plugs use high-grade alumina ceramic and a copper core to control temperatures and provide reliable starts. They are recommended where fine-wire iridium OE plugs are specified and often include features to ensure even electrode wear.
