NGK Iridium IX spark plug targets the performance-minded motorist, offering extreme ignitability, improved throttle response and strong anti-fouling properties. A fine iridium center electrode and tapered-cut ground electrode support better starting, idling and acceleration while iridium’s high melting point adds durability. Trivalent metal plating helps resist corrosion and seizing for easier service life and consistent spark delivery.
