I wish I had shot a picture of the air box prior to cutting... I may pull the one out of a CaymanS in the shop right now for an engine rebuild just so you can see the before and after.
Guy's.. buy a new one from Porsche. Trying to find them used right now is going to be difficult.
I posted the part number and the price in a previous post. They are not expensive new.
