What’s the verdict on MPG when removing front tire air dams-without changing tires and rims?

[McCloud_Rainbow]

I know a lot of folks who remove the front air dams are also changing tires, racks, wheels, etc. which all have an impact on noise and MPG. I would like to remove the front air dams, but keep my stock FE wheels, etc. My only concern is reduced MPG and/or increased noise for something that is a purely aesthetic decision.

Has anyone removed them and kept the rest of their LC stock and tracked the impact? What’s the verdict on this? Again…looking for data answers, not aesthetic preference.

Thanks!

I removed the air dams and did not notice any noise change nor do I notice a noise change with new 35's.
