NGK BCPR6EP-N-8 Spark Plug (Stock No. 5275)
The NGK BCPR6EP-N-8 is a high-quality platinum spark plug designed for stable ignition and long service life. It uses a fine platinum centre electrode to improve spark efficiency and reduce wear, helping the engine start cleanly, idle smoothly, and respond well to throttle. The resistor design cuts electrical noise that can affect the ECU and sensors.
Heat range 6 is a medium rating, suitable for many everyday petrol engines and mild performance setups. The projected tip places the spark deeper into the combustion chamber for better flame growth, aiding drivability and fuel efficiency.
Use this plug where the engine calls for a 14 mm thread, 19 mm reach, 16 mm hex, gasket seat, and a 0.8 mm gap. Always confirm fitment against your vehicle’s specification using our site’s vehicle lookup or check the Vehicle Fitment tab.
Why choose this plug
- Platinum centre electrode – longer life and consistent spark over time
- Resistor type – reduces radio/ECU interference for stable running
- Projected tip – helps cold starts, idle quality, and mid-range response

In the words of the Vehicle Standards Agency (VCA), type approval provides "confirmation that production and samples of a design will meet specified performance standards".
For emissions components this encompasses noise, emissions and balanced back pressure, which have a strong influence on maintaining engine performance (power), and fuel efficiency. Type approval ensures that an aftermarket component will reach, or exceed the performance standard of the corresponding OE part.
Type-approval then, is a certain guarantee that an end user will receive a product of OE equivalent performance attributes.
Products on the Progressive Parts website that meet this approval will be clearly marked or labelled EC or ECE approved.
