air box mod - smooth intake?

When putting in the 3" pipe for the intake, does the pipe have to be smooth and straight? Of course PVC is by default, but other materials (and flexible piping) may have course/rough interior and may not be arrow-straight.
My impression is that it's not like an exhaust. For the intake, you don't need to worry about how smooth the air is coming into the airbox. The air is already turbulent and under pressure (when driving), so smoothness of pipe doesn't give any benefit. It's only once air has been smoothed (by say a pump like the turbo) that need to worry about smoothness and straightness of piping (for example, a sport exhaust/downpipe). Am I right? Thanks!
