well first off i can be wrong about this so if im wrong correct me.......im sorry to announce that i dont think they make a CAI for anything older then 95.....but you can make your own.....its not very hard at all......
I have a 91 and they don't make one for it.. But like z24eurostyles said.. Very easy to make or get done. Should only cost you like $200 to $300 to get.. Its just a nice shinny tube with a filter on the end that grabs that so needed cold air ;-)
