There seems to be an overall benefit (how much is still being argued...)
Im thinking this would be a much more beneficialmod for those in high temp areas... Az is usually 105 deg+ for the summer months (upward (of 115 certain days). I noticed my intake temps rise REALLY fast at idle (ie 30 degree jump in a matter of seconds) so I would think every little thing to help air temps in these types of climates would have even more benefit.
Im in for this one. Did it on my old civic with no freezing issues (did not see much benefit though lol) but it does make a lot of sense for a turbo car. Im gonna try anything at this point....
