HKS Super SQV4 BOV Black Edition - 2002-2007 Subaru WRX / STI

The Black Edition SQV4 Sequential BOV is an effective way to quickly purge excess boost on the Subaru WRX/STI. 

RallySport Direct proudly carries quality performance products from the pioneers of the sport compact industry, HKS. 

 

For those of you who love that flagship HKS SSQ BOV chirp, here is the latest version which is the SQV4 Black Edition Blow-Off Valve. The popular pull-type relief design works quickly to purge boost between shifts to keep that turbo spooling or to quickly relieve the boost under deceleration. A great upgrade especially for those of you with power or boost levels that otherwise surpass the limits of the factory diverter valve. 

The SQV4 will come with a factory-like mounting flange to make this ready to bolt on, and it will come provided with a vacuum line as well as plugs to allow the user to vent this blow-off valve to the atmosphere.
