Cold air intake for '93 Legacy???

Hey everyone. I just got a nice 1993 Subaru Legacy with 107k on it about 3 weeks ago. I have since been looking for mods and have found that they are very hard to find. The one thing I really want is a cold-air intake. On www.xcceleration.com I found a Mass Air Flow adapter which "allows you to build your own cold air intake. However, I really dont know much about cars and on the site it says the Cold air intake bolts in at the end of the MAF. However, what next? Are there any CAI that just bolt onto this thing or is fabrication required?? Help! I have only seen cold air intakes for 1995 and up!!?!!?!
