When I took my wheelwell resonator out, I looked at the possibility of putting a foglight ram air tube in. Unfortunately there's a fender mounting bracket that makes it hard to get any decent sized tube from the foglight hole to the intake passage.
I also did some calculating and concluded that at 100 MPH, the total wind force against the front of the car is around 400 lbs or less, which means the average ram pressure is only 0.1 PSI! Of course, pressure at the bumper will be higher while pressure on the windshield is lower. But it looks like there's not a whole lot of point to a ram intake at less than racetrack speeds.
I still have an itch to try it, though. It has to be better than the stock plastic resonator with its ~58mm intake opening.
(What I've got now is half a resonator -- the thing was press-fitted together, so I unsnapped it and I have the part that mounts in the inside wall, but the wheelwell chamber is all open on one side now.)

mods so far: CTA intake with homemade heat shield, KVR drilled front rotors & carbon pads w/ 500° fluid
planned mods: exhaust (want to keep it quiet), e-ram (awaiting installation), diablo chip
involuntary mods: compression increased after head gasket failure
