NGK GR7CI-8 Spark Plug (Stock No. 95476)
The NGK GR7CI-8 is a high-quality performance spark plug designed for stable ignition under hard use. It suits engines that run hot or see frequent high revs, delivering a strong, reliable spark with clean combustion.
A fine iridium centre electrode reduces the voltage needed to fire, which helps cold starts and throttle response. The resistor design cuts electrical noise that can affect ECUs and sensors. A motorsport-style cut-back ground electrode improves flame spread for consistent burn.
Use this plug when you want dependable ignition in fast-road or track conditions. It is commonly specified for certain performance motorcycles and small-capacity tuned engines. Always confirm fitment with the vehicle lookup or the Vehicle Fitment tab.
- Stable spark at high RPM and high temperatures
