Turbosmart Kompact Plumb Back Blow Off Valve

The Turbosmart Kompact Plumb Back Blow Off Valve (also called a recirculating BOV, bypass valve or diverter valve) is a performance upgrade for turbocharged engines. It replaces the factory valve, and in many applications that valve is plastic. This fully recirculating design sends excess boost pressure back into the intake system instead of venting it to the atmosphere. You get the pressure-relief benefits of an aftermarket BOV without the loud blow-off sound.

Key Features:

• Fully recirculating plumb back design: routes all excess pressure back into the intake. This makes it a quiet option and suits cars with sensitive airflow metering.
• Durable aluminum construction: built for strength and flow under boost, and designed to hold up better than factory plastic units.
• Tolerance-matched piston and body: the moving parts fit precisely, which supports consistent, reliable operation.
• Bolt-on design: the Kompact line is made as a direct replacement for the factory valve. Versions with a flange suit applications where engine bay access is tight.
• Adjustable operation: many versions let you tune valve response to your setup, so you can match it to your boost level.
