The NGK Iridium IX spark plug delivers extreme ignitability, outstanding anti-fouling and durability for modified or high-performance use. Its fine iridium tip and tapered ground electrode improve starting, idling and throttle response while withstanding high temperatures. Trivalent plating and triple seals provide corrosion resistance and reliable service life, making these plugs a preferred upgrade from OE nickel alloy spark plugs.
