Along the lines of letting hot air out, there is a lip on the left and right side of the hood, which sort of slots into the fenders.

Some folks over on IFSJA have reported success, by bending it up flat, and allowing air out between the fenders and hood. Can't say for sure how it works, as I have never tried it, but it looks promising. Figure it would amount to an 1/8" gap, roughly 3 feet long, on either side.
