GFB TMS Respons Blow Off Valve Kit for Select Subaru 2003-2014 (Impreza / Legacy / Forester) T9001

Fits select 2003-2014 Subaru Impreza, Legacy, and Forester models.

The GFB TMS Respons Blow Off Valve Kit (T9001) is engineered to solve the drivability issues often associated with atmospheric venting on Subaru platforms, such as stalling and backfiring. Featuring GFB's patented venting bias adjustment, this valve allows you to control the proportion of air recirculated into the intake versus what is vented to the atmosphere. This ensures you get the signature blow-off sound while maintaining the smooth operation of a factory recirculating valve.

Utilizing GFB’s Turbo Management System (TMS) technology, the Respons is designed to minimize turbo lag by keeping the compressor spinning during gear changes, resulting in significantly faster boost recovery and sharper throttle response. Constructed for extreme performance, this valve is tested to withstand boost pressures exceeding 100 psi.

• TMS Technology for rapid boost recovery and improved throttle response
• Capable of holding 100+ psi of boost pressure
