Well I tried workin with a short ram CAI system from Ractive for a 99+ focus and well it works awesome as long as you modify the AIT sensor a bit and do not reset your comp..
for some odd reason when i reset my computer it made me have a huuuuuuuge lull from 3500 on till peak, so if you modify the intake to make you AIT sensor fit and dont reset your comp I think you may be fine, but my car is also a 95 so i have the OBD I, so I cant say much for the OBD II..
