the best thing is to use it as a aftercooler, in front of the pipes. ideally, a pre-cooler coming out of the head would be more efficient, but it's all hot air there. either way, it's only like 1-2 degrees difference, which can't really be proven, or noticed. best thing is to make sure the radiator is clean, the coolant is in good condition, and the jetting/fuel is right for your mods
