NGK BR10EIX Iridium IX Spark Plug – Stock No. 6801
The NGK BR10EIX is a cold heat range iridium spark plug designed for high performance and high revving engines, especially two-stroke applications. It provides a strong, consistent spark and better ignition under load. The fine iridium tip needs less voltage to fire, which helps cold starts and throttle response.
This plug resists fouling in stop-start use and at idle, while holding up well at sustained high RPM. It is a direct replacement for standard BR10 plugs of the same size and reach, with improved durability and a sharper spark.
Use this plug where a heat range 10 is specified. If unsure, use our vehicle lookup or check the Vehicle Fitment tab.
- Sharper, more reliable spark from a 0.6 mm iridium centre electrode
- Better ignition stability and cleaner running under load
- Long service life vs standard nickel plugs
