I know the downside is cutting the plate, but with my intake manifold, it's almost mandatory anyway.
With the engine idling, you might be able to get a little bit of cooler air into the engine. As soon as you start to drive the car, the air from under the car is going to force its way up and out, which will overcome any cooler air that you might get from the area above the rear deck. If you want to see how the air flows, just put some yarn on the rear deck outlet area, then have someone follow you. When I tried that on my Pantera, the yarn was being pushed straight out at less than 5 mph. It proved what I had already suspected about the air flow pattern, but it was a fun test anyway.
