Use it during your break-in and your adjustments, hot enough, it has the right temperature to make adjustments and break-in or to run your original engine in cold weather or even pushed (kite). It is not made for extreme performance or for heat. This model R has a 5 kOhm resistor for regulation and protection, it will therefore be accompanied by a 5 kOhm resistive interference suppressor.

- B = Ø14mm base (to be tightened with 20.8mm key)
- R = With 5 kOhm resistance
- 8 = hot thermal index
- H = thread length 12.70mm (short base)
- S = Central copper electrode
