Hey guys, I was over on e90post and stumbled upon a DIY for tapping a 1/4 NPT fitting onto the intake manifold to allow a larger diameter for proper operation of a BOV.
I have a ER charge pipe/Tial BOV on order and should be arriving soon.
Have any of you done this to your intake manifold?
Could I just use a larger inside diameter hose than OEM?
Thoughts?
