Is this the hose (smaller photo) you folks are talking about? Then it's a BC3Z-6F073-A.
A steel H&S is a good replacement, shown below. You just need to make sure you get the correct one as they have two versions - one for a 'chipped' engine, the other for stock. There is at least one other and probably more better ones then the stock one, and all $250 or so bucks vs $175 up for the OEM (plus labor if not a DIYer)
