I'd be in for something like this - but does feel more like a sub- $400 thing...

Looking at the view from underneath the car, I wonder if that messes with that mini diffuser/duct looking thing in front of the rear bumper...



I looked it up to see what that part is and RealOEM says that it's a "cover, activated charcoal filter"? Makes no sense. Anyone know what it really is? Part #17
