GReddy "FV2" Blow-off Valve GDB Made in Japan, original GReddy item "Plug & Play" kit for Subaru Impreza GDB (02-07) Engine code: EJ20 High manufacturing quality Fast response and maximum reliability Adjustable trigger pressure and 360° rotating body Type: recirculation and atmospheric venting Made of forged aluminum GReddy part number: 11561214 Specifications of the GReddy FV2 Black blow-off valve kit for Subaru Impreza GDB Introduced in 2021, this GReddy blow-off valve is a direct evolution of the previous GReddy FV generation. Still manufactured from forged aluminum and based on a dual-piston design, this new version features a revised layout while ensuring 100% backward compatibility thanks to its perfectly identical flange and dimensions. A new manufacturing process ensures even greater reliability and brings two major innovations: The opening pressure of the GReddy FV2 blow-off valve is now adjustable with a knob. The blow-off valve body can rotate 360° to facilitate installation in tight engine bays. The new black GReddy FV2 blow-off valve ensures both a stable idle and an extremely fast opening and closing time, even at low boost pressures. These unique capabilities guarantee maximum reliability for any type of use, all while optimizing turbo spool (maintaining rotation speed during gear changes for improved response time / anti-lag properties). This kit for the Subaru Impreza GDB was developed and approved by GReddy in Japan, and contains everything needed for a plug & play installation. It allows for two types of installation: recirculation or venting to the atmosphere.
