HKS’s blow off valve, the super reliable, great sounding blow SSQV version 3 has been discontinued and HKS is moving onto a newer version called SSQV 4.
SSQV 4 will be identical in operation to SSQV 4, the primary reason we think HKS moved onto the SSQV 4 is to keep ahead of all of the counterfeiters and knock off blow off valves.
