There must be a reason. I doubt its for sound, mpg or emissions. Maybe the ribs cause just the slight amount of turbulence actually needed for smooth air intake flow. I also wonder if maybe smooth tubes are beneficial on forced inductions vehicles? Ive had numerous intakes both CAI and SRI as well as silicone tubes on the VQ.

I think they OEM tubes are there to allow for any engine movement.
Example, my old fox body mustang had an aftermarket cold air intake (drew air from the fender). It was old so the motormounts were a bit worn. Every now and then if I shift a gear hard enough the tubes would pop loose from the silicon couplers.
