seriously this is what my car needed(2009 JCW Coupe), my old blow off valve was starting to go bad... so i picked up this guy, this paired with a CAI will make sure everyone knows your running a turbo.

I installed the Cravenspeed "Big Pair"today. Huge difference, just what the F56 chassis needed. Well made and very easy to install.
