Stock BPV or forge BPV?
I know I could easily google this but what are the real tech's opinions on this? Obviously the stock one is plastic and obviously the forge is steel but is there any real difference with the KO4? Running approximately 24 psi catless dp, Hahn charge pipes ✌ðŸ»

Forge BPV and ZZP intake is my set up for the HHR SS. Like one of the post above said I only replaced it due to the diaphragm being torn.
