Hello,
So in reading the list of mods that can help increase MPG. I have some questions related to aero mods. I'll ask them one at a time so as to not complicate getting answers.
I saw this picture shown in the list of efficiency mods.

Its clearly increasing the frontal area of the truck. Because its bigger than the stock front end. Granted it does cut more air going under the truck. But its still bigger. So I have to make the assumption that it made a difference or else it would not have been chosen for this list.
Can anyone explain why this air dam above is better than me running one of these air dams specifically made for my truck?
