I had to replace the lower half of my air box. I ordered a new one, the non-aero (only other one available) for my 2005 9-3 arc. I started installing it, and the lower hose that goes into the bottom doesnt fit. On the old air box, the lower hose goes inside the air box, on the new one, its fitting around the lower hole in the air box. Has anyone else had an issue or did they just change the design? I don't understand.
