Dump valve / Blow off valve

A piston operated dump valve does a better job containing your precious boost pressure. Compared to the original membrane operated dump valve you will notice a snappy-er throttle response and you will now be able to throw all of your boost at the engine instead of leaking it back.

The saab-tuners dumpvalve seals even better than regular piston operated dumpvalves because of the added leak free rubber seal.

We are very exited about this newest product and hope you are to at this limited time introduction price.

The boost valve comes with 3 different springs and a 2mm ring to set up the tension to your car's liking.
