GFB – Respons TMS Dual Port Blow-Off Valve
Description
The GFB Respons TMS (ref. T9003) is designed as a direct bolt-on blow-off valve for the Subaru Impreza WRX and WRX STi. GFB's patented TMS (Turbo Management System) venting bias adjustment gives you precise control from 100% recirculation (silent) to 100% atmosphere (full blow-off sound). Boost recovery is up to 30% faster than the factory diverter valve during gear changes, even on sensitive MAF-based systems. No modifications required — everything needed for a bolt-on install is included. Compatible with WRX and WRX STi.
