GFB Deceptor PRO II Blow-off Valve/BOV/Diverter Valve (T9503)


This is a BRAND NEW GFB Deceptr PRO II (T9503) blow off valve that will bolt directly to the factory mount of the models listed below.

The Deceptor PRO II system allows for adjustment between recirculation and venting to atmosphere by adjusting the single port between the two options, much like the GFB Respons valves. However unlike Respons, Deceptor Pro II valves allow for adjustment from inside the cabin through a motor attached to the valve and a small adjustment dial in the cabin.

Comes with everything needed to fit to your car.

GFB T9503 BOV suits the following vehicles:

Subaru WRX Impreza/STi (GDA-GGA & GDB-GGB) MY01-03/MY03-07 EJ20T/EJ25T

Subaru WRX/STi (GR) MY08-on EJ25T

Subaru Forester XT (SG) MY05-08 EJ25T
