NGK ZFR5BIX Iridium IX Spark Plug – Stock No. 93274
The NGK ZFR5BIX is a fine-wire iridium spark plug designed for reliable ignition, clean combustion, and long life. It helps cold starts, smooth idle, and throttle response. It also resists fouling in daily use and maintains a stable spark under load.
Use this if your engine requires a 14 mm thread plug with a projected tip and gasket seat. It suits many modern petrol engines that specify NGK heat range 5 plugs. Please use the vehicle lookup to confirm fitment, or check the Vehicle Fitment tab for full details.
- 0.6 mm iridium centre electrode for a strong, consistent spark
