There is a rumor that the pre-vanos intake manifold is very similar in construction and engineering as the dinan intake manifold that sells for $1500 for the 540i.

96-98 intake runners would do. don't have to be 97's or Dinan's where they take the OE part and bore it out or take the 96-98 runners and stamp their name to give it the extra 2000% markup.
