Is cold air intake really worth it?
wow this thread is so off track.
By ram air do you mean just sticking a cone filter in the engine bay like on that link? if so you would be sucking in very hot air, I have personally tried it just to see and I actually lost power all over and MPG. the engine bay gets really hot on the exhaust side. There only gain is aesthetic and that is arguable, you will loose performance.
The stock airbox is a cold air intake (CAI). that means at the front there is a tube that goes under the headlight and sucks in cold air from outside the engine bay. This will give you the more power vs hotter air. The stock airbox for an N/A is not that restrictive especially with a drop in aftermarket filter, I have seen turbo setups using the stock airbox even.
The only thing that would be better is a larger cold air intake, which is the BFI cause you are making the area it brings in cold air from larger.
Either that or you extend the piping into the fender area (have to cut a hole under the stock airbox location) and put your cone filter there, that would also give you more cold air, but will be more prone to catching water if you like to take your SC through small lakes.
In summary; More hotter air = bad and more colder air = good

try this out, run your car for 30 min, then pop open the hood and put your hand near the distributor (where the injen ram air sits).
This is possibly the hottest place in the entire engine bay. you are loosing valuable power and increasing your chance for knock, which makes the ecu pull timing madly. I have actualy owned all 3 setups.

that is exactly what I am saying. Even the stock setup is better than the ram air. don't oil the filter though, it will hurt the maf eventually. just run it dry.

Good luck with your hunt tho....
K&N or APEXi or Blitz drop-in air filter + dremeling the airbox = best bang for your buck. I always ran Blitz drop-ins with the BFI. I never went as extreme as the BFI setup is supposed to be; I just dremeled the front of the airbox as big as i could. Later I snaked about a foot of fireproof ducting under the headlight and attached it to a velocity stack that i rigged and mounted just behind the air inlet on the passenger side of the front bumper (97+)
