NGK BP5EY Spark Plug – NGK Stock No. 7327
The NGK BP5EY is a non-resistor spark plug with a projected tip and V-grooved centre electrode. It uses a copper core for good heat transfer and a nickel alloy electrode for reliable spark. This design helps cold starts, smooth idle and consistent ignition under everyday driving.
It suits many older petrol engines that use a 14 mm thread and 19 mm reach. Please use the vehicle lookup tool or check the Vehicle Fitment tab to confirm fitment for your engine.
- V-groove electrode focuses the spark for cleaner combustion
- Projected tip improves flame kernel start and throttle response
- Copper core helps control heat and reduces fouling
