06 325i Manifold Conversion (E90)

jacob.fr7 · Today, 01:07 PM

Hey All,

I just recently took ownership of a new daily, early build 06 325i manual (n52)

Im a bit confused on whats required for a 3 stage manifold conversion. I have a manifold from a 330i that Im ready to swap in. However I believe my 06 build has a single port while the 3 stage manifold is dual.

What additional parts do I need in order to use the 3 stage manifold? I haven't been able to find the parts needed.

I think I got the software bit figured out.

If your manifold doesn't have the DISA valves you need them- DISA Valves 11617579114, 11617560538
You need the 2 port breather hose but if your CCV hasn't been changed to your knowledge you may as well replace the oil separator and all the hoses. The 2 port hose is- 11617559530
