I've looked at the pic some more... love the tubing changes...no more tapering "saxophone or nasty looking plastic, although I wonder why not 2 separate tubes from the box, 1 to each turbo. A great improvement I think.
IMHO... still believe a closed filter box is the way to keep underhood air (not cold) from entering. The air should be drawn from outside the engine compartment via large bore closed tubing (piping like the pic) to have the coolest air possible. Mike B and I discussed this development idea today over at Black Market Racing/Full Race... I think we may get going on the development again as soon as the cutouts are ready.
