sparker,
I've got quite a few interior CF parts that I bought from a couple of Porsche dealerships and a few eBay sellers. All of the parts are OE except one that may or may not be OE. This one part matches the OE parts exactly but I haven't seen it listed or pictured anywhere else which makes me question its origin.
Like Kirk I've seen and read about the OE stuff yellowing and cracking. I've had some of these parts in the car for several years and thus far I've been lucky. People seem to love or hate CF. I love it and think it works well with my grey interior.
