The NGK Spark Plug CR9E features a central electrode with copper deeply embedded in the tip, enabling fast dissipation of high heat quantities to deter overheating and fouling.
KEY FEATURES:
- Copper-cored electrodes effectively disperse the heat produced during combustion away from the firing end.
- This quells hotspots that can lead to pre-ignition
- It also features an extended insulator nose that prevents fouling.
- OEM Quality
- Triple-Gasket Sealing Process
