NGK BPR9EIX Iridium Spark Plug – Stock No. 6853
The NGK BPR9EIX is a cold heat range iridium spark plug designed for reliable ignition under high load and high revs. Its fine iridium tip needs less voltage to fire, helping cold starts, throttle response, and combustion stability. The projected, resistor design supports cleaner running and reduced electrical noise for modern ignitions.
This plug suits engines that specify a 14 mm thread, 19 mm reach, gasket seat, projected tip, resistor, and NGK heat range 9. It is popular in many high performance motorcycle and 2-stroke applications. Use the vehicle lookup to confirm fitment, or check the Vehicle Fitment tab for full details.
- Fine-wire iridium tip for strong spark and long life
- Cold heat range 9 for high temperature, high load use
- Resistor design reduces radio interference and ECU noise

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.
