Features & Product Details
RallySport Direct proudly carries quality performance products from the pioneers of the sport compact industry, HKS. They are one of the pioneers of aftermarket performance products!
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.
