Whats up guys, I have a 2005 s40 T5, and I really want to put a BOV in it but I'm not exactly sure what kind to get and what mods need to be done, can anyone help me out?

 

As far as other mods go....none. You can install this but it needs to be welded to an IC pipe either after the turbo or before the TB.

These are suppose to be pretty good:

But most people use Greddy Type RS or HKS SSQV:
