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

Delivery timescales are given as estimates in good faith, but cannot be taken as precise or exact information. We highly advise against booking installation/workshop time or engaging in preparatory work until you've received and inspected the goods.
What do our stock statuses mean?
1+ IN STOCK in green stock is readily available in one of our warehouses for express delivery (at the time of viewing).
LOW STOCK in green means we're running low! 1 or 2 left on the shelf so act fast. Over evenings, weekends and bank holidays this stock can move quickly so please bear this in mind.
0 IN STOCK in blue means our primary warehouse does not have unallocated stock, but our UK partners do. Often these can be shipped quickly and efficiently. You'll be notified via the Track My Order page if further delays are unavoidable.
MADE TO ORDER in blue means we've partnered with a supplier which primarily makes their products to order. It's not on our shelf, but your order goes into production immediately.
0 IN STOCK in orange means everybody we work with is unfortunately out of stock. Stock is not available in the UK. The best course of action is to place an order to create an allocation from the next batch arriving.
OUT OF STOCK in red. This product is unavailable to order, for whatever reason we're unable to obtain stock or there is an issue with supply/lead times.
We're tuners too!
Our staff are car enthusiasts, we understand the need for speed... This includes getting your orders out the door as quickly and securely as possible!
In some instances, extended lead times are unavoidable. This is as labour-intensive and frustrating for us as it is for you, please know we are doing our best to facilitate your modification goals. Abuse of our staff or systems will not be tolerated.
Thank you, Team PP
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.
