NGK BCPR5EP-11 Spark Plug – Stock No. 2097
The NGK BCPR5EP-11 is a platinum centre electrode spark plug designed for clean ignition, smooth running, and longer service life than standard copper/nickel plugs. It is a resistor, projected-tip plug with a factory 1.1 mm gap, ideal for everyday road use and mild performance upgrades.
You can expect reliable cold starts, a stable idle, and consistent combustion under load. The projected tip helps the flame start in the best position, and the built-in resistor cuts electrical noise that can affect the radio or ECU.
- Sharper, consistent spark for smoother running
- Longer service life vs standard plugs
- Resistor design reduces interference
Note: The plug is pre-gapped to 1.1 mm. Check the gap for your engine, but avoid forcing adjustments on fine-wire platinum tips.
