I'm not an an aero geek, but I'm a chemist. The pressure differential created by raming any air requires the system to be sealed. Last time I looked I can see pavement out of the engine bay bottom, so there's no way you're going to do harm under the hood, except to move additional cooling air into the bay, and push hot ai out the bottom.

My guess is it will aide in cooling the engine compartment better, a thermocouple and an electronic thermometer could answer that.

As for those of us who have CAI the possibility that you'll pull in hot under the hood air would be less with this as well.

Ater looking at their website, I hate to rain on any parades; but I favor not messing around too much with airflow and aerodynamics, which Chevy did a significant amount of time optimizing; I'd be interested in knowing EXACTLY how much their products affect the downforces of the car. Did they do any wind tunnel studies to come up with optimized products?
