Howdy - Ol' Bubber agin ...
After a second look, it looks like that ductwork would do a very good job of ADDING heat to the intake air - aluminum, and in the very best spot to absorb high underhood temperatures.
Here's a way to find out - you have a Livewire (with full datalogging of all PID's as part of the functionality) - log IAT's during yer normal stop&go routine. Do it with the scoop 'active', and repeat the routine with it blocked off.
Note any differences and post 'em up. I'm genuinely curious. Overly high IAT's kill power; the PCM pulls timing to save the motor and in extreme cases dumps in more fuel fer cooling.
At speed ( steady ~40 mph and above), there is so much air exchange in that largely open engine compartment that this issue of elevated IAT's would be moot.
Awaiting some data. Git 'er did, Cooter!
Cheers!

Route: 20 minutes. 2 stop lights through town, then a long stretch of 50km/h - 60km/h - 80km/h - 60km/h - park and idle for 1 minute.
Run 1: Scoop Open
Ambient Temp: 37F
IAT Low/High: 34F/48F
Run 2: Scoop Closed
Ambient Temp: 37F
IAT Low/High: 40F/54F
Run 3: Scoop Open [Again]
Ambient Temp: 36F
IAT Low/High: 34F/44F
Here are the screens so I don't have to type everything else out:
Run 1:
Run 2:
Run 3:

Boy would I have a hard time cutting that hole in the hood, its makes me cringe just thinking about it. Cool to see though man, it'd be interesting to see how much those differences in intake temperature affect hp and mpg.

Creativity seems to be a disappearing thing in today's world. This is definitely creative and it'll be pretty awesome if it proves functional.

Thanks . So far, seems to be working as intended. No squeaks or rattles from the duct on the underside of the hood, either. Everything's buttoned-up and tucks in nicely.

And as for MPGS, mine are always garbage because of the sequencing of the lights in my town. Before the intake and scoop, I averaged about 14 MPG. My friend's got a bone-stock 2007 Escape with the 3.0L V6, but rarely uses the highway, and he gets worse mileage than I do.
