Fuck all that reading, I'll just post this as proof you can "hack" your bumper, have it look good, AND have AC. Or at least the parts for AC, as I smashed the car before I got it recharged.
Oh and the best part, I used an HF manifold. How anti-AC is that?
That JRC intercooler is ~2.75" thick at max
FYI you need to move the aluminum lines in front of the radiator, move the condensor back a tad, rebend a few lines, cut a big notch out of the bumper support, and a little sheetmetal. The bumper support really doesn't do shit, my car nosedived and went underneith the other car, and that was with tokico shocks & bald steelies.
