The Turbosmart Kompact Plumb Back blow off valve offers a bolt on, recirculating solution. These valve will hold more boost, consistently. It's stealthy look and construction makes it a great addition to any engine back and retains a stealthy sound for those not looking for the noise of a Vent to Atmosphere (VTA), valve.
Unlike with VTA valves, you won't require any other modifications or the pesky drop in revs and occasional stalling associated with them. It's a great valve that you can install in minutes.
