i am usually on e90post but a lot of us who own 325is like to do the 3 Stage Intake Manifold. The BMW X3 3.0si has the intake manifold of interest.
I was wondering if it was possible to completely swap my 1 stage manifold for an X3's intake manifold. Obviously the 3 stage will fit my car no problem.

But will my 325i intake manifold fit the X3 without any issues or errors? Here is the part list that i will be swapping from the X3.

11617559523 Intake Manifold
11617559530 Vent Hose
11617579114 Adjustor Unit
11617560538 Adjustor Unit 2
11617547242 Gasket set
11617535850 x2 Screw 50x35
11617535849 x5 Screw 50x20
11617535851 x1 Screw 50x66

325i has a special pipe for the oil cooler under the manifold. X3 does not have one. The 325i manifold may have an extra opening for the cooler, so that is where the modification lies.

It may be nothing & really just about hoses. The 325i hoses are very fragile and people say to buy a spare to be safe.
