He asked this for me.
I just opened up my airbox and took a look around. I didn't see anything that restricted airflow except the actual .. well. this is how i understood it to work from looking at the parts.
air comes in from the front of the car through the grills / fan and enters a funnel or snorkel to travel to the airbox where it's stopped by a wall and forced below the air filter. it passes through the filter and then is moved along to the rubber tubing or whatever connects it to the engine.
nothing at all that was removable looked like it was in the way.
am i looking in the wrong place?
