I know most air dams are functional and are necessary to divert airflow and keep the front grounded. But it seems too high off the ground to really do much. In my head I can’t see it as anything more than drag.

It also seems too flimsy to actually act as front end downforce. Would I removing this do anything negative or positive?

 

Yes, it redirects air up to the radiator and A/C condenser. It is absolutely sturdy enough for the job.

It also serves as an early warning system, as it protrudes lower than the oil pan and other sensitive bits, so you’ll hear that catch on stuff before those more critical components take damage. This is especially helpful on a lowered car.

As for aerodynamics, I couldn’t say. You’d need a wind tunnel test to know for sure, but I’d guess it’s a net benefit overall. That said, fluid dynamics is incredibly complex and often surprises even people who have studied it for decades. Best bet here: trust the factory engineers.

 

It definitely assists engine cooling, via directing airflow through the radiator. Take it off, and watch the coolant temp soar at freeway speeds.

 

Oh that makes sense. I don’t know why I didn’t think of that. Thank you.
