Front Air Dam Provides Air Flow to the Engine?

I'm no engineer, but isn't the air dam a mute point when a truck is lifted/lowered? I imagine it was designed to move air under the vehicle at a certain height off of the ground.

Pretty much , I would agree with you

Not mute, but maybe moot

Without CFD or windtunnel data, it's just speculation on the effect on a lifted/lowered truck.

I've had mine off for a few months and even on a hot day I don't see the temps go up any. I think it's just to help with air flow around and underneath the truck for better mpgs. Even then I've only noticed maybe 1 mpg less at the most on the interstate. Mileage didn't change at all in town or on the highway with speed limits of 45 and 55.

 

Also lets be honest, it's 2015, I highly doubt they would rely on a piece of plastic on the bottom of the bumper to help airflow for cooling. My 98 didn't have that problem and my '14 hasn't either. I really think it's just for mpgs, even if it's less than 1 mpg.
