I haven't seen a rise in temperature at all. The intercooler sits up behind the grill so you're not blocking it at all.This is awesome! I have been looking at doing this as well. I am not worried about relocating the ACC, but I cannot find anything on how it does, or does not, effect any cooling. The winch sits right in front of one of the coolers (all though I am not too clear on which one it is).
