Well for starters this is not a naturally aspirated car, it's forced induction, the cold air the flows in will be heated instantly by the turbo. Now if you were to lower the temps, by say 30+ degrees then yeah you might see a bit of a hike in power, but I doubt any CAI can do that. Also 100's of people have made good power without one. You'd be better off spending money on a good tune, and following the same basic upgrade path that most do. Trust me you'll be happy in the long run and so will your tuner. Not trying to be an a$$hat, just trying to point you in the right direction and save you and your tuner alot of headaches.
