Brand
GO FAST BITS
The GFB Respons TMS T9003 is a direct-fit diverter and blow-off valve for selected Subaru WRX and STi models. Its adjustable venting bias system lets you control the balance from full recirculation (quiet) to full atmospheric venting (loud), without the common drivability issues.
- Direct bolt-on replacement for the factory bypass valve
- Adjustable venting bias – recirc to atmosphere (and anywhere in between)
- Improves throttle response and boost recovery between shifts
- Compatible with WRX and STi models listed below
- Subaru WRX MY01–02 (Bugeye)
- Subaru WRX MY03–05 (Blobeye)
- Subaru WRX MY06–07 (Hawkeye)

GFB Respons TMS T9003 Diverter / Blow-Off Valve – Subaru WRX & STi (MY01–22)
Adjustable Diverter / Blow-Off Valve for Subaru WRX & STi
The GFB Respons TMS T9003 is designed for Subaru WRX and STi applications listed below as a direct replacement for the factory bypass valve. It combines performance-focused valve control with a venting bias adjustment that lets you dial in the sound and behaviour you want.
Control the Blow-Off Sound Properly
Many MAF-based cars can run poorly with a full vent-to-atmosphere valve. The Respons TMS solves this by allowing you to adjust how much air vents to atmosphere versus recirculates back into the intake. You can run it near-stock and quiet, or open it up for more blow-off sound.
Better Response Between Shifts
The valve is designed to vent only what’s needed, helping preserve boost where possible and supporting faster boost recovery after gear changes. The result is a sharper, more consistent throttle feel.
Direct-Fit, No Fabrication
This is not a universal weld-on valve. The T9003 is supplied as a bolt-on solution for the compatible Subaru models listed below, fitting in the factory valve position.
