The NGK Iridium IX spark plug is tailored for the performance-minded driver, offering extreme ignitability, improved throttle response and durable anti-fouling characteristics. A fine iridium center electrode provides long-lasting, consistent spark performance and durability far beyond platinum. A tapered cut ground electrode improves starting and idle quality while NGK's ceramic insulator, copper core and anti-corrosion plating help manage heat and protect against seizure for demanding applications.
