The NGK Iridium IX spark plug is an upgrade aimed at drivers seeking sharper throttle response and improved fuel economy. A fine iridium tip and tapered-cut ground electrode promote extreme ignitability, better starting and reduced fouling. NGK pairs a durable alumina ceramic insulator with trivalent plating for corrosion resistance, making Iridium IX a long-lasting option for modified or spirited applications.
