I am curious too! Mostly I'm worried about highway speeds.. it may help heat soak at stand still but does it take longer to cool it down once you're rolling?
mite as well install a sprayer wile you are in there..Alright I have my bumper off and measured how much room between the i.c is and the shroud and it's 3/4" clearance. So very very small amount of room for air to pass. I did take a few pictures close up of the shroud on the i.c to give a idea of how much room there is stock wise. I am going to take it off and take a few more pictures of it. I will post them in about 30 min to a hour
