NGK BR8HIX Iridium IX Spark Plug – 7001
The NGK BR8HIX is a high-quality iridium spark plug designed for reliable ignition and long life. The fine iridium centre electrode needs less voltage to spark, which helps cold starts and stable running. It also resists fouling, which is common in two-stroke engines, and keeps performance consistent over time.
This plug suits many performance two-stroke and small-capacity engines that use a 14 mm thread, 12.7 mm reach and a cold NGK heat range 8. Use the vehicle lookup to confirm fitment, or check the Vehicle Fitment tab for full details.
- Stronger, cleaner spark for smoother idle and better throttle response
- Iridium fine wire for long service life and reduced misfires
- Resistor design to cut electrical noise that can affect electronics
Always set the gap and torque to your engine manufacturer’s specification.
