The NGK Iridium IX spark plug is tailored for the performance-minded driver, using an iridium fine-wire center electrode for extreme ignitability, anti-fouling and extended durability. A tapered-cut ground electrode improves starting, idling and throttle response while iridium's high melting point suits high-temperature engines. Iridium IX promotes quicker acceleration, better fuel efficiency and reliable spark delivery for modified or high-performance applications.
