On the traditional intercooler's they will not cool with/out air moving through them and when in the trees doing technical riding in deep snow there is not near enough air moving through the intercooler to be efficient. So instead they become heat soaked and make it worse. It also increases lag from having more charge tube displacement. For my kind of riding I would only use a water to air cooler, or none at all. But I guess if you race across lakes and always cruise at 50+mph any cooler would work.
