There's so many ways to do this and everyone's going to have their own opinnion on what's the right way.
You could make a "cold" air box out of metal flashing and some door trim gasket. I fabbed one up for my '96 SHO that way. Make a cardboard template first, then cut it out of the metal flashing. The thing is that a metal "cold" air box acts as a heat sink, transferring the engine bay heat through the material and into the air box. Had a remote thermometer in my cold airbox and the temps under hood and in the box were the same when the car was sitting still. When the car was moving, the temps dropped in the box; but it was the same difference as just relocating the filter to below the engine bay or into the fender. You'd have to wrap the box with something that would deflect the heat.
Ideally, you'd like to scavenge air from a high pressure area of the car... either behind the bumper, headlight, fender, or from the lower portion of the windshield where it meets the hood. The engineers usually have the right location, we're just looking for more volume.
You never get any sort of ram effect unless you're going 160 mph. If you're looking to just cool the intake charge, look to relocate the filter somewhere out of the bay. Heat's always going to be a problem, and you'll never completely defeat it.
