I could be wrong but that's what this looks like.. it looks like an active shutter system that allows air to go through the radiator.. It also appears to direct air flow up and through the airbox. It appears to pull air from behind the ford grill logo as well. That's alot of ram air already designed by ford engineers. Again, I could be speculating and be completely wrong but I think this ram air from the factory should be more than enough.
On the Last 2 times I made a ram air system I actually used a 4inch to 3inch adapter to collect air in a header fashion 4 into 1 with the 1 being a 3 inch to 2 inch pipe going into the air collector/ stock box.
example of previous collector design using a header as the inspiration=
