NGK Iridium IX Spark Plug BCPR6EIX-11 (Stock No. 4919)
This NGK Iridium IX plug delivers a strong, reliable spark for smoother idle, sharper throttle response, and consistent performance. The fine iridium centre electrode needs less voltage to fire, helping cold starts and high-load running. It also lasts longer than standard copper plugs.
Key benefits
- Fine iridium tip for a clean, stable spark
- Improved starting and response under load
- Long service life compared to standard plugs
