can one use medium on-road plugs in off-road ?
Normally off-road plugs are a long body plug. As for on road 1/10 sedan I only use the short body plugs (novarossi 6TGF).
I think there would a slight difference in performance between a long and short body plug of the same heat range.
Pass you soon...
