NGK Iridium IX spark plugs are precision iridium-tipped plugs engineered for high-ignitability and durability, offering improved throttle response, starting and fuel efficiency for modified or high-performance applications. The fine iridium center electrode and tapered ground electrode resist fouling and wear, while trivalent plating aids corrosion resistance, making them a reliable upgrade over OE nickel plugs.
