well, ive been looking for one for my 88, and one thing you might want to consider is that your car is speed density, not mass air. so you have no mass air sensor, which means that most of the cold air kits (c&l etc.) are not made for your model stang. i did however check into the
FOXBOX from CHICANE, and they DO make one for mustangs with speed density (all mustangs before 89, except CA cars). but it would probably be wise just to go to the junk yard and get a stocker for now, because youll end up converting to mass air eventually, and then your cai kit will be obsolete.
