    Forgemotorsport - have a look at their website

    Are you planing on tuning your S3? no real point fitting an uprated dumpvalve if it is not really required.

    Then you will definately need an uprated dump valve to cope with the extra boost!

    Bear in mind they are not "dump valves" - no air can be dumped on the S3's recirculated system as excess air is shot back into the intake.

    If you want a valve which will hold boost better after tuning you want a new DV ("diverter valve") - go for either Forge or OEM Revision H.
