I have a 3-stage intake manifold from a 2006 330i for sale. $200 or best offer, shipping included. $25 discount for local pickup (near LAX airport).
I removed and inspected both DISA valves and they are both not functional. The shaft is loose on the bottom of the large valve, and on the smaller valve the flap has some rotational free play. I recommend rebuilding or replacing with new DISA valves prior to installation. Not pictured but included is the heated elbow for the CCV connector. The manifold itself is in great shape with no cracks.
