it sure looks alot easier to install than the REVI, at least not having the needs to take off the front bumper I would think you still need to take off the bumper to get the VFAD out of the equation. I don't see any point at all in installing an intake and leaving it there unless all you want is hot air.

On the downside of the airbox, RB themselves says on their website that "enlarging the oval inlet to the factory air box - +2 HP (this modification eliminates the VFAD intake duct.)."

I agree that the airbox only works as a tuner for a limited range, however it's effectiveness is there for more than 1000rpm. Kind of like bandwidth on an electronic circuit.

Enlarging the oval, simply tunes the box to a different rpm range. Port size is a very important part of resonance tuning. Removing the box entirely will not add the 2 hp that came from enlarging the port.
