The NGK Iridium IX spark plug is a high-ignitability option for drivers seeking better throttle response and fuel efficiency. Its fine iridium center electrode and tapered ground electrode improve starting, idling and acceleration while offering strong anti-fouling and durability. Trivalent plating helps resist corrosion and seizing, making these plugs a durable upgrade over standard nickel options for modified or high-performance use.
