Can I swap my (I think M52 mani) for an M50 or S50, If so which, and is there a kit I can buy to do it with? My serial number is BY23698 for real oem. I know its very dependant on whether you have a TU or not and which vanos you have.

Ok thats fine, I dont want to go crazy I've just heard that the stock one is more restrictive than the m50. Will it just not line up? Thanks anyway :thumbup:

My, we're bitter this morning! THis is untrue... if you have a M52 engine.

The M52TU (which from 1998/09 on is what the 528 has) is incompatible with the M50 intake, but the M54 intake DOES work, so find a 330 or 530 intake to work with. Also look up the performance section on e46fanatics.com. There's a few NA builds in there that have done this.

For full enjoyment of the new manifold, you'll need headers and a chip too.
