NGK BPR5ES Spark Plug – Stock No. 7422
A reliable, standard NGK spark plug for everyday driving and light performance use. The BPR5ES uses a projected tip and a resistor to help reduce radio noise and improve idle quality. It suits many older petrol engines that take a 14 mm, long-reach, gasket-seat plug. Always confirm fitment with the vehicle lookup or see the Vehicle Fitment tab.
- Stable spark for easy starts and smooth idle
- Nickel electrodes for long service life in standard tune engines
- Projected core nose helps cold starting and throttle response
