The NGK Iridium spark plug delivers dependable ignition performance and long service life by combining a fine wire iridium center electrode with precision manufacturing. Designed for drivers who demand crisp throttle response and improved cold starting the plug's iridium tip provides a consistently strong spark that helps optimise combustion for better fuel efficiency and reduced emissions. Its robust construction resists wear and maintains a stable spark gap over extended intervals so maintenance is less frequent compared with conventional plugs.

Built to meet strict original equipment tolerances the plug offers straightforward installation and dependable operation under a wide range of driving conditions. Corrosion resistant plating on the threads and a durable electrode assembly ensure reliable contact and easy removal at service time. Ideal for motorists looking to upgrade from standard plugs or maintain peak engine performance the iridium design balances longevity with reliable ignitability for everyday driving and spirited use.
