NGK APR6FS Spark Plug (Stock No. 2922) – 686
This NGK APR6FS is a resistor, projected-tip copper spark plug designed for stable ignition and long service life. It offers reliable cold starts, clean combustion, and consistent performance in everyday driving and spirited use.
The projected insulator places the spark in a more efficient position in the chamber, improving throttle response and helping reduce fouling. The resistor design cuts electrical noise that can affect radios and sensitive electronics.
- Strong, reliable spark for smooth idle and clean pull through the rev range.
- Projected tip for efficient flame kernel and better drivability.
- Resistor type to reduce electrical interference.
