Wow. Look at all the cool [censored] I missed being in Iraq!
I think that manifold design is a TERRIBLY expensive and piss poor way to do what ford already did with the 3L Taurus/Escape manifolds; basically give all six runners equal access to a common plenum! Not to mention the new manifolds are all plastic if you are worried about heat flow.
Dumb and costly, especially considering the restriction from the throttle body inlet to the narrow box. There is a reason a cylinder is more efficient than a square box at flowing liquids(air).
The corners will stall out lots of air reducing the effective area that the flowing air will actually "see", the narrow opening will create quite a bit of drag even thought the surface area is high.
I have better manifold concept sketches at home in my notebook.
