"More air" only means more power if the engine can consume that air and use fuel to make the power. This "more air equals more power" idea generally means someone doesn't understand how engines work. The factory airbox has more than enough CFM to feed this engine's demands NA. The tune is where it's at. I pushed my fully loaded '12 into the 11s at 115+ on just a mild 91 tune, through the factory paper filter and airbox, with factory exhaust and GT500 mufflers.
