NGK BPR5EKU Spark Plug – Twin Ground, Projected Tip
The NGK BPR5EKU is a reliable upgrade for everyday performance and long service life. It uses a projected tip for clean combustion and easier cold starts. The twin ground electrodes help maintain a strong spark for longer, even under tough conditions. The built-in resistor reduces electrical noise that can affect the radio or ECU.
This plug suits many petrol engines that require a 14 mm thread, 19 mm reach, gasket seat, and NGK heat range 5. Always confirm fitment with the vehicle lookup or check the Vehicle Fitment tab.
- Strong, consistent ignition with twin ground electrodes
- Projected tip aids throttle response and cold starts
- Resistor design cuts interference for stable ECU signals
