The NGK Iridium IX spark plug targets drivers wanting improved throttle response and fuel economy. Its fine iridium tip and tapered cut ground electrode increase ignitability and reduce fouling for better starting and idling. Iridium’s high melting point provides exceptional durability; NGK pairs this with a copper core and alumina silicate insulator for heat control and reliable dielectric performance. Trivalent plating protects against corrosion and seizing for easier maintenance.
