No, gcwimmers has a tube going into the engine bay and stopping. Its not connected to a box or the filter itself so anything that does go up it most likely will get lost in the engine bay. From the diagram shown yours has a box with a hose attached that flows down to the bumper so its all sealed of from the engine bay.
I dont know of anyone with a closed box and a hose running from it. Myself, Sully and Pektel talked about trying to use the stock box that way but no one ever did it. Everyone has either a shield or the pipe work runs from the MAFS to behind the bumper and thats where the filter sits. Or, like gcwimmers.
I see what you are saying. Same concept except we are talking about being totally sealed. Did you guys cut a larger opening from the hole that is under the air box? I know some guys didn't want to be cutting away metal but that's really the only way to get a decent sized pipe through there. I think when I do mine I am going to make a fiberglass enclosure that I can make larger than the stock air box and it will fit in that area better.
