GFB TMS Respons Blow Off Valve Kit for Select 1998-2005 Subaru Impreza, Legacy, and Forester XT (T9000)

The GFB TMS Respons Blow Off Valve Kit (T9000) fits select 1998-2005 Subaru Forester, Impreza, and Legacy models. Designed for drivers who want the signature blow-off sound without the performance drawbacks, this kit solves the common issues of stalling and backfiring often associated with fixed-ratio atmosphere-venting valves.

Featuring GFB's patented Venting Bias Adjustment, you can fine-tune the ratio of air returned to the intake versus air vented to the atmosphere. This ensures you can achieve the desired sound while maintaining smooth engine operation. The valve utilizes GFB's proprietary Turbo Management System (TMS) technology, which is engineered to provide rapid boost recovery during gear shifts and significantly sharper throttle response. Built to handle extreme boost levels, the Respons is pressure-tested to withstand 100 psi or more, making it suitable for any turbocharger configuration.

• TMS Technology: Optimized for faster boost recovery and improved throttle response during gear changes.
• Adjustable Venting: Patented bias adjustment allows for a customizable atmosphere-to-recirculation ratio to prevent engine stumbling.
• High Pressure Capability: Engineered and tested to hold boost pressures exceeding 100 psi.
• Vehicle Fitment: Replaces factory valves on 1998-2005 Subaru Impreza, Legacy, and Forester XT models.
• Manufacturer Part Number: T9000
