About this part

GFB's Respons TMS BOV, short shift kit and pulley package fits the 1999–2000 WRX/STi, with a dual-port blow-off valve, a 55mm third-to-fourth shift throw at its shortest setting, and 6061-T6 billet aluminium pulleys for crank, alternator and power steering plus two belts. The valve's adjusting ring lets you dial between fully recirculated and fully atmospheric, which is how GFB keeps the sound without the stall that comes from venting a MAF-metered car's full charge.

Fitment
