NGK Iridium IX spark plugs combine a fine‑wire iridium center electrode with a tapered ground electrode to deliver exceptional ignitability, improved throttle response and strong fuel efficiency. Iridium’s high melting point supports long life and anti‑fouling properties, while trivalent plating helps resist corrosion and seizing. Recommended for modified or high‑demand applications as an upgrade from OE nickel plugs.
