Could it not just be caused by the higher air dam and bigger gap? They should at least have some effect.

The front wheel wells get some warmth from the engine btw.
My front brakes are usually warmer because they take most of the brake load.

Also, a 'slightly favourable' wind needs to be straight aft to really give you a benefit.
Side wind ruins the aero properties of your car much more than even straight ahead.
I get my best economy on windless days and not (even) when the wind is blowing aft.

On my morning commute the usual wind direction is 45 degrees left.
In the last few miles I turn into the wind, and fuel economy rises considerably.
Going back home the first part is pure bliss, then economy falls sharply when the wind strikes at 45 degrees aft.

For confirmation go to people just like you.
For education go to people unlike yourself.
