THE POPULAR HKS SSQ GETS BETTER

This is the HKS Black Edition SQV4 Sequential BOV. This is the grandfather of blow-off valves with its flagship sound that remains to be one of the most effective blow-off valves in the aftermarket. This blow-off valve reacts very quickly to purge excess boost while creating that flagship HKS blow-off valve chirp. A great upgrade over the factory diverter valve in your WRX
