Where exactly? There is no wall shown on the piccy above. Right hand side of the picture is the lower where the outside air comes in.
Might be worth a quick piccy of what you have on your 2.

Yes, but other side of airbox....    There is a plastic  wall right next to intake hole.     I just disassembled my car and took this picture...

This  what you are thinking of doing?

Looks like there is no gain in performance or induction noise.

in principle it gives you less restriction to pull air through the filter, so arguably a benefit

the 911 guys do something similar never had experience of it on a roadster though

I did a test some years ago, about the Air Box and the Smoothing effect the Air Filter does on the MAF reading..

I was under the impression that the Air Horn did all the straightening of the Air that was necessary..  

I was wrong..  the Air filter is nessasary in the Air Box..  so no..  you cant hack it up and get better gains..

Here is the Post where I did the work..
