Help with intake manifold ID, 996 3.4L X51?

[Sci3ntist]

Hey guys, new member here.. I'm a Porsche/ sports car tech down here in SoCal and need some help identifying a few parts. I have an intake manifold and runners off of a 3.4L, parts are dated 2000, 2001. The manifolds are aluminum- something I have never seen on a few hundred 996s that I've had come throught the shop and the local dealers could not ID the part numbers for me!! I have heard of a super rare 3.4L X51 kit that was available in Europe but info is limited. I'm wondering if anyone on here can possibly clue me in on any other info on these parts, any help is greatly appreciated!

have never seen a set of them in black before. All of the 3.6l or 3.8L X51 cast manifolds are raw casting. Those casting numbers do not always cross over to the part number. I would expect the first 9 numbers to be the beginning of the part number but the 1R and 0R are likely replaced by a two digit number in any Porsche parts diagram or PET software. I believe the 3.6L part number ends in a 40.

The paint job definitely looks suspect so I was trying not to base any conclusions on that alone. As far as the casting numbers not exactly matching part numbers, I had suspected this but was not sure, thank you for your input.
