I read on fc3s.org about how to build an air box, but if you build the box shouldn't you run a duct to the outside (where the fog lights should be for ex.) to get cooler air than is in the engine bay? or should I do a duct from the fan ( I have the e-fan mod). any suggestions would be helpful.
I'm actually curious about this. Any less extreme solutions than the one outlined above?

I have not installed my cold air box yet due to lack of time. I did change the headlight cover on the passenger side headlight to one of the inlet duct covers (Mariah Motorsports). I admit I paid way too much for the inlet cover but it looks good and was professionally made. It was too much money though, thinking about it after the fact I have seen them made for far less. This allows air directly into the area of the cold airbox. The airbox will have a rubber seal with the hood of the car so it will be relatively closed off from the engine bay. Not a perfect seal but good enough for what I need.

I actually like the inlet cover headlights, but I am short on $$ for that, but I looked at Lowe's last night on what it would cost to build one like the box on fc3s.org and it would cost about 26 bucks, what I have decided to do is to make the box and mount it where the washer fluid box is (I don't have wipers so it is useless to me) and run a 2" PVC pipe underneath to the grill area and enclose my box with a lid and I will have a cold air intake, if there are any more suggestions I would sure appreciate them. I will be post pics when I am done I am going to start on it tommorow after work.

I mean a cold air box on a normal RX-7, not one of those beasts, lol.

A BIGGG waste of time on a N/A.

actually it's questionable how useful the headlight cover really is. You'd be better off with a cowl hood or if you ran ducting down low on the front of the car where the brake ducts and radiator inlet are, the headlight covers are at a negative pressure area, at least at the speed this image represents:

From that graph, it looks like the brake duct and front "mouth" are the best places to pick up air (yeah, master of the obvious) so running a duct to the cold air box from there should work well.
