On a '92? I wouldn't choose any of them. For the price you would pay for an intake the gains you get are minimal at best, if you're lucky. I'd just pick up a different tube to the air cleaner (got mine at home depot...4" non-perforated drainage pipe), then a K&N drop in and call it good. $35 total instead of $200+, and you get the same gains.
