The NGK Single Iridium (Iridium IX) spark plug upgrades ignition for drivers seeking improved throttle response and durability. Its fine iridium tip provides extreme ignitability and long life, helping starting, idling and acceleration. Trivalent plating reduces corrosion and seizing, while the construction supports use in modified or high-performance setups as an upgrade over OE nickel plugs.
