NGK BR7HIX Iridium IX Spark Plug (Stock No. 7067)
The NGK BR7HIX is a high-quality iridium spark plug designed for strong ignition and long service life. It uses a fine-wire iridium centre electrode to produce a clean, reliable spark with less voltage demand. This helps cold starts, reduces fouling, and keeps performance consistent over time.
Iridium is a very hard, heat-resistant metal. It wears slower than standard nickel plugs, so gaps stay stable for longer. That means fewer replacements and more consistent running between services.
Broad fitment guidance: common in many motorcycles, scooters, ATVs, karts and small performance engines that use 14 mm short-reach (12.7 mm) gasket-seat plugs in NGK heat range 7. Always confirm with the vehicle lookup or the Vehicle Fitment tab.
Why it matters
- Fine-wire iridium tip for a strong, focused spark and easier starts
- Better resistance to fouling in stop-start or high-load use
- Stable gap for longer, helping maintain smooth idle and throttle response
