i have an AFE magnum force air box and it does make turbo more prounced but you will notice it more when you get a tuner and turn the tune up. the only thing is to use a tuner you should have an high flow airbox.
hope this sheads some light on it.

Go to the 7.3L forum and search KwikFilter or 6637 mod, many pages of info and pictures on a great low cost set-up, or try clicking this link...

Just checking... I've seen people do such things. The downside to an open filter element is you're breathing superheated under-hood air, rather than at least partially breathing cooler air from the outside world.
As far as real performance, a true ram-air hood induction system would net you the most benefits.

On his year he has the ram air passing through the battery box and it would hit the 6637. The temps are only about 18 degrees hotter that the outside ambient air. And that would be the temp going into the stock anyway.
I've measured, measured, and measured.
The 7.3 works fine, in fact better with the open air filter.
