Like all GFB valves, the Respons utilises GFB's proven TMS Technology to ensure rapid boost recovery on gearshift and optimum throttle response, as well as the ability to withstand boost pressures of 100psi+. Put simply, it can hold more boost than any turbo could produce.Installation InstructionsThis Part Fits: Year Make Model Submodel 2004-2005 Mazda Miata Mazdaspeed 1994-1995 Subaru Impreza Base 1996 Subaru Impreza Brighton 1994-1996 Subaru Impreza L 1994 Subaru Impreza LS 1995-1996 Subaru Impreza LX 1995-1996 Subaru Impreza Outback 1993-1998 Toyota Supra Base 1993-1998 Toyota Supra Twin Turbo
