About this part

GFB's Respons TMS blow-off valve and short shift kit package is built for the 1999–2000 WRX/STi, with the third-to-fourth shift throw cut to 55mm at its shortest setting. The valve's adjusting ring opens the atmospheric port while closing the recirculating one, so boost can be set anywhere from fully recirculated to fully atmospheric, and GFB manufacture it to ISO 9001.
