Real Carbon fiber ducts
I was going to use these on the front fenders of my SC (but I'm selling the car now)
they actually fit the curvature of the front fenders

$75 + shipping

 

were exactly would they mount? have refernce pics?

 

^yeah were would this necessarily go?

 

Here's a mock up on a cardboard box,
the vent has a very thin gasket on the edge which helps it sit flush on the surface of the fender
(note: the box is completely flat, so the vent does not sit flush on it, but it's pretty close)

I was going to mount it in the same location as the vent here,
but with the hole on the trailing side (as opposed to the leading side in this pic)
