Hello, I would like some input on aftermarket bov's. I was reading the by pass valve thread & I have an 05fxt & I recently bought an usdm sti intercooler from a friend & he threw in an hks ss bov for a great price so i purchased them both. I tend to hear some good & not so good things regarding aftermarket bov's so I'd like to know if anyone has any opinions/experiences with them or more specifically the hks ss bov. I know that with atmoshere venting bov's the MAF can sometimes get screwed up due to the air being expelled & not accounted for but I had an 02 wrx with an sti intercooler a turbo xs bov a TBE,up pipe, intake & ecu tek remap & had no problems with it. I am planning on doing similar mods to the xt but I am weary of any potential problems. Thanks in advance for any help.
