A while back somebody mentioned the exact K&n filter model which fits in the original air filter box. And now I can't find the post anymore.
So, if somebody could tell me the model once more.

go to K&N's web site and they have a search engine to find the proper filter for the car.
Or you can call up your local pep-boys and order it from them.
Its a special order but they can get the correct one.
Just be sure to specify the model and the year IE: 1983 900 Turbo.

It all depends what you're going for. There are at least 15 models which fit on a saab. KN has a stat spreadsheet around somewhere for you to choose from.
