The NGK Iridium IX spark plug is crafted for drivers seeking stronger ignition and improved throttle response. Its fine iridium center electrode and tapered ground design enhance ignitability, anti-fouling and fuel efficiency, supporting better starts and idle behavior. Ceramic insulation and corrosion-resistant plating contribute to durability, making Iridium IX a recommended upgrade for modified or higher-demand applications that benefit from a high-ignitability plug.
