Turbosmart Kompact Dual Port Blow-Off Valve - Subaru WRX 2008-2014 (Excl STI) / Legacy GT 2003-2008

The Kompact Dual Port is a piston-actuated blow-off valve that directly replaces the factory bypass valve. Its billet aluminum body and precision-machined lightweight piston seal without rubber diaphragms or O-rings, so it resists the cracking and diaphragm failure common to aging OEM valves. The dual port design recirculates enough flow to keep the factory MAF metering correct while venting the rest to atmosphere, and it holds seal to guard against compressor surge when boost is raised.
