GFB TMS Respons Blow Off Valve Kit for Select 1997-2009 Audi, Saab, and VW (1.8T / 2.3T) - T9025

Fits select 1997-2009 Audi, Saab, and Volkswagen models including the A4, TT, 9-3, 9-5, Beetle, Golf, Jetta, and Passat (1.8T / 2.3T).

The GFB TMS Respons Blow Off Valve (BOV) Kit T9025 is engineered to provide the acoustic benefits of an atmosphere-venting valve without the common driveability issues associated with mass airflow (MAF) sensors. While standard fixed-ratio valves often cause stalling or backfiring, the Respons utilizes an adjustable venting bias. This allows the user to fine-tune the ratio of recirculated to atmosphere-vented air, ensuring the ECU remains satisfied while delivering the desired blow-off sound.

Built with GFB’s proprietary Turbo Management System (TMS) technology, this valve is designed specifically to maintain turbo RPM during gearshifts. This results in significantly faster boost recovery and improved throttle response compared to factory diverter valves. The precision-machined internal components are rated to withstand boost pressures exceeding 100 psi, making it a reliable solution for high-boost applications.
