The GM CAI is made by Cold Air Induction, comes with a tune from GM, and maintains factory warranty. All others have the potential to void you warranty.
CAI will not make a big performance gain until you start making other mods and tune the car. It is a little noisier, and I'd say throttle response is a little better (but that could be the noise playing with my experience).
For your $350, you could have Pray Performance port your throttle body, which is a better improvement than the CAI.
