Overview

The HKS Super SQV Return Pipe is a 29mm ID hose fitting designed to convert an atmospheric blow-off valve (BOV) into a recirculating valve. This component allows the released air to be routed back into the intake system, similar to a stock air bypass valve, which can help with street legality.

The fitting is constructed from stainless steel and is compatible with HKS SSQV (Super Sequential Blow-Off Valve) versions 1, 2, 3, and 4. It is a universal part, meaning it is not application-specific.
Show original supplier description
The HKS Super SQV Return Pipe (71002-AK004) is a stainless steel fitting that enables the conversion of an HKS Super Sequential Blow-Off Valve (SSQV) from an atmospheric vent to a recirculating system. This is ideal for users who wish to route the released boost pressure back into the intake tract, mimicking the function of a factory bypass valve and potentially aiding in compliance with emissions or noise regulations. This return pipe is specifically designed for a 29mm inner diameter hose. It is compatible with all versions of the HKS SSQV blow-off valve, including Ver. 1, 2, 3, and 4. The stainless steel construction ensures durability and resistance to the harsh under-hood environment. As a universal component, this fitting does not have specific vehicle applications. Buyers are advised to verify compatibility with their existing setup and hose size before purchase. It serves as a replacement or an add-on for those integrating an HKS SSQV BOV into their turbocharging system.
