Having more fun with my model and aerodynamic concepts.
When I first put it on it was level flat, and realized it was under the aero-template too much, plus could not open the engine lid. I curved it up to resolve both issues - could be a bit smaller/thinner in retrospect.
Also posted below if you need to see them a little larger.

Now look again at the below image, how the flow sneaks under the air-slot under the rear spoiler much as it does on the roof wing of my pickup truck.

I know that many of the images regarding my truck were lost to Photobucket's 3rd party BS including the CFD images, but the long and short of it is, the air getting under is accelerated and this draws the air above it downward.
In this case the backside of the wing/spoiler engages the airflow, causing a build-up of pressure, this pressure can escape downward and into the cooling vent, or attempt to fight the flow above and probably lose and end up as a vortex aft, which in turn would once again cause down-force and downward airflow on the engine lid.
All just my imagination at work currently, but this is much closer to being worthy of testing in some manner - in my opinion.
If I had to say this design reminds me of most, I'd say the New Beetle hoop wing.

I'm wondering if that would fit my car now.
