Personally I can't see an advantage for airflow though there, probably just the opposite and adding water as you drive in an area that's not designed to get excess water in there anyway.

Not that I am worried about water getting in there, but being I was already in there when changing out my fog light bulbs I did take the time to put a little dielectric grease on the plugs as an added safety measure.

Just something to consider if you make any changes.

Edit to add: Looking again at the pic above, it looks like its a little different than my 35i so the water comment may not apply in your application.
