Most people only change the air intake for 2 reasons,better sound or if they are dressing their engine bay to get rid of the crappy black plastic.
The ARC box does both of these and now sounds better since the re-map.
It's dual action so you will be fine,it's the rotary's you have to be careful with.Just start of with a finishing pad and polish,then step up until you get the correction you want.
Mine dyno'd yesterday at 280 bhp with ARC airbox,MREV2 lower plenum and 5Zigen exhaust.Paul managed to get it back to 296 and I'm really impressed with the way it goes now.
