Mopar intake or Volant would be my 2 top picks. S&B also offers a close system for a true cold air intake. Open elements aren't true cold air intakes and rob you of power when sucking hot air from the engine compartment.
The RT has the srt box and that pulls from the wheel well anyways. Throw in a K&N drop in and u should be fine. If you are going for looks at the expense of sucking in engine bay temps then go for any of the engine bay mounted open filter.... Then it's user preference as far as what flavor you want... If you are going for performance than I'd suggest LMI true CAI
Mopar cai all the way , you got a 2012 so you don't want to give the dealer an excuse to fish in your pockets. I gained about 11 hp, throatier hemi growl, smoother acceleration, and a noticeable boost during take off. It's only a little more than other cai's, you can find it from 400-420. It gives you everything you're looking for without voiding your warranty.
