GFB T9359 has been discontinued – replaced by T9381
Model T9381 covers all the T9359 valve’s compatibilities and extends them further.
Lower overall height for installation with upgraded intake systems
Many Mk7 Golf R and Audi S3 8V owners had to choose between an upgraded intake system and the GFB T9359 DV+, as both modifications required additional space. T9381 is the same height as the original diverter valve, so installation with an upgraded intake system is no longer a problem.
Integrated solenoid and simpler installation
T9381 has a low-profile integrated solenoid and is a complete direct replacement for the original valve. There is no need to disassemble the original diverter valve and reuse its solenoid, making installation quicker while also eliminating potential issues caused by wear of the original solenoid.
Suitable for: Audi S3 III (8V), Audi Tts III (FV), Škoda Superb III (3V3) / III (3V5), VW Arteon I (3H), VW Golf VII (5G1), VW Passat B8 (3G).
