About this part

GFB's Respons TMS blow-off valve and short shift kit package (T9003 + 4002) is built for the 6-speed STi from 2001 to 2014, cutting the third-to-fourth shift throw to 55mm at its shortest setting. TMS is GFB's Turbo Management System, controlling how much the valve vents and for how long rather than just dumping boost on every lift, and GFB manufacture it to ISO 9001.
