Product Description

The GFB T9225 Hybrid Dual-Outlet Diverter Valve revives GFB's original 1998 staged dual-port design - offering recirculation, 50/50, or full atmosphere venting via adjustable blanking plugs. It's engineered for turbocharged VW, Audi, and Saab 1.8 T engines from 1995-2009 and fits other Bosch-style systems using 20 mm hoses.

Constructed from robust CNC-machined aluminium and tested above 100 psi, this valve merges performance and refinement. TMS technology ensures quick boost recovery during gear shifts, while the staged outlets prevent compressor surge. The universal design includes direct-fit kits or hose-mount options - but installers must reverse Bosch valve orientation (boost enters base, exits side) per PDF instructions for proper function.
