Wow! What a simple install--having never worked on a Saab before, this installation took me exactly 60mins. Immediately I could hear the engine gulping more air on start-up, and yes, the turbo is finally audible inside the car! (but not noisy or irritating). I haven't yet checked milage or acceleration gains, but I know K&N's work well, so buy it!
