Mine are doing the same thing at 1,200 miles. Not turning grey, but rough and pitted. It looks like they have been pelted with gravel from the sand trucks, even though I don't drive mine in the snow. My only possible thought is that since the ducts stick out farther than the rest of the car they are taking a beating from pebbles even though the body of the car doesnt appear to be.
