Hey guys, new here and new to wrx ownership. Just got a ‘14 all stock, no mods yet. My list is long but one of the things I cannot find any answer to is the existence of a BPV SPACER. I have read multiple articles discussing such a device. From what I understand it is an additional plate or block that you can put under the stock BPV that allows it to act similarly to a BOV by venting a selectable (50/50 or 100%) amount of the air to atmosphere. I have not been able to find any products/reviews of such a setup but I’m hoping y’all can provide insight. On this same note, is there and aftermarket BOV that is selectable in the amount of air vented so as not to lose some of that pressure to keep throttle response? Thanks in advance.
