It fits the G, and it does retain the factor strut brace. 
Well, Kenetix sold 100's of sheetmetal plenums at about $900 for basically no gain. We have tuned a bunch of them, and they did not perform....sorry Kenetix.
If Cosworth can keep the plenum closer to $1K, and can demonstrate good power, it's a winner.
I think you guys know me well enough by now. If this thing sucks, I will not sell it...PERIOD. I dont get too excited by manufacturer's claims, but Cosworth is a world class engineering company...so I give them more credit than most.

I might be very interested if they release a polished version. Then maybe someone will buy my Kinetix's one for super cheap.

it's actually kinda similar to the stock plenum design if you think about it - but yeah the ducts are bigger/longer and the air box area around them bigger as well so should work pretty well.
looks pretty heavy though - at least as heavy as stock, even if the sides are CF
