Wait, those things were actually put on there?? I thought that something fell down that I needed to repair/replace I like that idea though.
Yup, their function is to move air current around the car/truck rather than under it, it cleans up the aerodynamics of the car. You will see that the newer the car the larger/lower the air dam is, on many late models its just part of the front bumper/fascia
Most Small Curbs and parking bump stops for me....
I installed a factory air dam on mine, but moved it to the very edge to direct more air up into the coolers vs cleaning on the air underneath.
I still have the factory one in the shed, this one is nearly twice the height and reaches from tire to tire, quite a difference. I could just barely notice a difference at speed, I'm curious if it will make any difference at all in fuel mileage, we'll see after I get a few thousand miles on it like this.
