HKS HKS Suction Return Kit - Recirculating Conversion for SQV Valve

This Recirculating Conversion Kit from HKS converts a HKS SQV Valve from functioning as a vent-to-atmosphere valve to a recirculating valve.This means that instead of venting excess pressure to atmosphere with the distinctive dump-valve sound the charge is instead returned to the intake, silently.You still get all of the advantages of the HKS SQV Sequential Blow-Off Valve, but keep your car stealthy making this combination perfect for sleepers.
