Product Description

The HKS 71008-AT020 SUPER SQV4 is a vehicle-specific blow-off valve kit developed for the Toyota GR Yaris GXPA16 and its G16E-GTS 1.6L turbocharged three-cylinder engine. The kit uses HKS's sequential valve structure to deliver the characteristic SUPER SQV4 blow-off sound while providing a dedicated installation designed around the GR Yaris engine bay.

The kit replaces the factory intercooler outlet-side resin piping with a dedicated HKS cast-aluminum outlet pipe. This construction is designed to reduce the risk of expansion or damage associated with aging factory resin piping. The factory air bypass valve can remain in use rather than being cancelled when the SUPER SQV4 is installed.

A suction-return hose is included, allowing the system to be configured for recirculated operation. HKS confirms the GXPA16 application through March 2024 and specifically states that vehicles manufactured from April 2024 onward have not been confirmed for this part. The 71008-AT020 should therefore not be assigned to later GR Yaris production or GR Corolla applications without additional manufacturer confirmation.
