NGK BKR7ESC-11 Spark Plug (Stock No. 6313)
This NGK spark plug delivers a strong, consistent spark for reliable combustion. It uses a copper core with a nickel alloy tip to pull heat away from the firing end. That helps resist fouling under hard use and keeps performance steady. The NGK heat range 7 is a relatively cold rating, suitable for many performance-focused or turbocharged petrol engines that run hotter than stock.
Expect smoother starts, cleaner idle, and stable ignition at higher loads. A new plug will not add power by itself, but it can help you get back lost performance if your old plugs are worn.
Use our vehicle lookup to confirm fitment, or check the Vehicle Fitment tab for full details. Compatibility depends on thread size, reach, and hex size matching your engine’s cylinder head.
Why choose this plug
- Reliable spark and good heat control for fast road and tuned setups
- Resistor design reduces electrical noise that can affect sensors and the ECU
- Preset 1.1 mm gap for many modern petrol engines, adjustable to your spec

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.
