NGK BPR7E Spark Plug – Stock No. 1142
The NGK BPR7E is a reliable copper-core spark plug with a projected, resistor design. It offers consistent ignition performance and good heat control, especially on tuned or hard-driven petrol engines that call for a colder heat range. It is a direct replacement where BPR7E is specified.
- Strong spark and stable idle thanks to copper core and projected tip
- Resistor design reduces electrical noise for sensitive ECUs and audio systems
- Heat range 7 helps manage higher combustion temperatures in performance use
