I am planning to buy a 3 stage Manifold for my 328i. It already has the bimmerlabs tune and all it needs is the manifold. I am only worried about the DISA valves and rebuilding it or buying a new one. I am looking at Benzeen auto parts store who sell parts online with 1 year warranty and free shipping.
Do I have to rebuild it or what are the steps? If it comes with a DISA valves from 2011, is there no need to rebuild or replace? Help Much appreciated! Trying to keep it in a budget under $400. Not trying to buy additional DISA valves with my manifold!
