TiAL Q Blow Off Valve - 2 psi (green) Spring, Blue Body, Stainless Steel Flange

I absolutely LOVE this BOV!!! I'm using it on a Procharged mustang GT so the 2psi Spring is perfect for the centrifugal supercharger! This thing is LOUD!!! And it responds way quicker than the other blow off valve I used to have. Just make sure that the vacuum line feeding it is big enough, or it won't respond fast enough at all.
