Yea a cold air. and not a chip a good tuner . Sct and edge are popular options. Then there's the option of getting custom tunes

 

Idk how much this costs but you could put a performance cam in it with performance valves and rocker arms but ur gas milage will go out the window

 

Cam alone with probably be around $900, but you also need an egr delete and a bunch of other stuff. Plus install you're looking at about at least $1500. But you should definitely be running a CAI and exhaust before you go cam. Lol Plus you would need a custom tune with the cam which would probably be another $200 or so dollars.

 

Intake, exhaust, custom tune; you're ready to roll.
