The Turbosmart Kompact plumb-back blow-off valve is a compact recirculating valve intended to return excess boost to the intake tract rather than venting to atmosphere. Marketed as Kompact Plumb Back, it offers a low-profile solution for turbocharged setups that require retained boost recirculation and tidy underhood packaging without altering boost control behavior.
