This is my favorite ugrade, I wasn't really up for "modding the airbox" like some saabbers recommend, so I decided to just get an open air intake. I do not regret this purchase at all, sounds great (especially with the forge twin piston blow-off valve to release all the pressure it builds up)

I originally had just a drop in K&N filter, which helped turbo spool a little, but this dramatically increased turbo spool for me. It also looks good under the hood. I used the stock airbox screws to install this, it just seemed right.
