NGK BPR6E Spark Plug – Stock No. 6464
The NGK BPR6E is a reliable, copper core spark plug for everyday road use and light performance tuning. It offers steady ignition, good cold starting, and stable idle. The projected tip helps efficient combustion, while the resistor design cuts radio interference.
Use it where a 14 mm gasket-seat, 19 mm reach plug is specified. It suits many older petrol engines from mainstream manufacturers. Always confirm with our vehicle lookup or the Vehicle Fitment tab before ordering.
Why choose this plug
- Strong, consistent spark for smooth running
- Copper core for better heat control under load
- Projected tip improves flame kernel and throttle response
- Resistor type reduces electrical noise affecting radios and ECUs
Always set the gap and torque to your vehicle’s spec. Incorrect fitment can cause misfires or engine damage.
