interesting idea.

I have a few thoughts - first, I don't think the size is NEARLY big enough. Keep in mind you are taking 1/2 of the waste heat of the entire 450 horsepower engine, and thinking it will go through that little hole, after the air has gotten hot. I think you are a factor of 20 off.

Second, I'm worried about air coming back along outside the tire, and "stacking up" on the fender - you might find you need to tip the lower part of the fender "in" below your vent to get a vortex to keep the air outside of the fender.

Third, I think a MUCH more interesting thing is to look at the chin spoiler. A chin spoiler in front of or even with the radiator will keep the air out from under the truck giving the air somewhere to go.
