Instant reliability for every journey

From the high-revving demands of technical backroads to the steady cruises along Surf Highway 45, NGK provides the reliability that Taranaki riders trust. Their premium Iridium and Racing plugs are engineered to withstand the extreme pressures of modern engines, ensuring a complete burn of the fuel-air mixture for maximum power. This brand is famous for its Triple-Gasket sealing process, which prevents combustion gas leakage and ensures that the plug remains securely seated even under heavy vibration. A standout hallmark of NGK is their "Niterra" advanced ceramics, which provide superior insulation and strength, preventing the electrical flashover that can cause misfires in the damp West Coast air.

Ensure a reliable start and peak ignition performance with NGK Iridium IX spark plugs.
