This is a discussion on FS: APEXI twin chamber BOV within the Personal For Sale & Wanted forums, part of the ClubWRX.net Marketplace category; I'll throw in the flange and piping so it's already mounted ready to go. Looking for 0 shipped for everything. ...
is it a universal of set up for wrx/sti, and what year if so?
it's universal. there's an adjustable screw/nut on top of the bov that u can give it more tension or have it loose tension depending on how much psi's your pushing.
