n52b30 intake manifold
I have been looking at the n52b30 intake manifold since it’s better but alittle and why not get the biggest one. But looking at the manifold there’s the CCV valve and a vent with it. Question is can you bypass the vent and go with the stage one CCV hose or no? When buying the manifold I will be getting new disa values so I don’t have to worry about them. Any suggestion with the disas?

BMW OEM Disas only. They cost more, but will last the lifetime of the car. I've seen cheap ones fail and do weird stuff. You want to look for the 2 aos port version. I believe only early 2006s had the single port intake manifold.
You can remove the whole pcv system from the intake manifold as that is integrated in your valve cover

"Vaico" sells aftermarket DISA valves, even has some Youtube videos about them but they have mixed reviews in the forums. I went with OE when replacing my two DISAs (Euro N52).
