The NGK Iridium spark plug delivers reliable ignition performance and long service life for modern petrol engines. Featuring a fine iridium center electrode and a robust ground electrode, it provides a concentrated spark for faster flame propagation and improved combustion efficiency. The precision engineered tip reduces voltage requirements and enhances cold start response while maintaining stable idle and throttle response under load. Designed for replacement and performance upgrade applications, this plug gives consistent firing and reduced misfires over extended intervals.

Manufactured with corrosion resistant plating and a high quality insulator to resist fouling, the unit is pre-gapped to 0.9 mm and incorporates a resistive core to suppress radio frequency interference. Its medium heat range and durable electrode materials make it suitable for a wide range of light duty and high demand driving conditions. Fitment requires standard installation torque and basic hand tools, and NGK recommends inspection at regular service intervals to maximise life and performance.
