BRZ, FRS & 86 2012+ Aluminium OEM Turbo Blow Off Valve

Product Description

AVOTurboworld Billet Blow-off Valves are essential to reliable performance for turbocharged engines.  As you build air pressure in your system (boost), it can suddenly find itself with nowhere to go when you let off the throttle or in between gear shifts.  Once the throttle plate closes, boost just builds up with no exit point but to go back through the turbocharger.  So a blow-off valves job is to vent all that built-up pressure back into the system or out to atmosphere. This allows the turbo to continue spinning freely.  This is important not just for pressurizing the air going into the engine, it is also important for the exhaust gases going out of your engine as they run through the turbo exhaust side to spin it up. 

Modern ECU's on todays cars compensate for the amount of air that has been dumped back into the air flow system, and when you simply remove that air, it leads to idle problems as it throws the system off temporarily.  Our OEM style aluminium BOV will work perfectly with modern vehicles.
