The plastic itself gets really hot, especially when driving in 90 degree weather, and being black and all it seems to me it would retain more heat in the engine compartment when having it on.

I've measured the underhood temerature differential with it on and with it off using a remote pyrometer as well as monitoring the IAT values on highway runs.
The underhood temps drop several more degrees with the cover in place. That heat is directed out the vents on the sides of the fenders with the cover in place.
With the cover off, the temps peaked at 178°F and dropped to 115°F in 3 minutes.
With the cover on (and after letting the compartment idle heat-soak again), the 3 minute drop was all the way down to 98°F.
This was with an 89°F ambient.
This won't be registered by your in-dash thermometer. Its sensor is located in front of the left-front wheel at the bottom of the bumper.
Additionally, it protects the paint on the hood and the hood itself from the heat - remember, it is aluminum and conducts heat differently from steel.

Only idiots are too impaired to be aware that they are indeed, idiots.
That is to say, by your proclaiming that you are, you aren't.
And conversely, those that deny that they are, are.
And let me close in proclaiming my own idiocy.

Thank you. :p

Jeff,
Thanks for sharing your scientific results.
If you're in the mood for it, collect some mpg data, etc (with your laptop setup) on driving with the sunroof and windows open at highway speeds vs with all closed and A/C on please
.
Hope to see you at the MSCW (www.mscw.com) meeting 09.01 .
