Installation Instructions for GFB Respons (part # T9001) Covered vehicles: • WRX MY08-on • GT Liberty/Legacy MY03-on • XT Forester MY09-on 1) Remove the 4 fasteners that hold the plastic engine cover using the Phillips screwdriver (GT Liberty/Legacy only). Lift the engine cover off and set aside. 2) Using the 10mm socket, remove the two bolts holding the factory bypass valve to the intercooler, then use the pliers to open the hose clamp to remove the plumb back hose (fig. 1).
Typically, most Subaru engines will allow 100% atmosphere venting with no problems. However, some combinations of modifications can result in backfiring when the valve vents to atmosphere, in which case the solution is simply to dial back the amount of air vented to atmosphere until the problem is resolved – this is one of the key benefits of the venting bias adjustment feature. Do not be afraid to experiment with the spring and noise settings, no harm will come to the engine if wrong setting is used.
Maintenance GFB blow-off valves are designed to be as maintenance-free as possible. In most cars the small amount of crankcase and rocker-cover oil vapor that is directed into the intake system is enough to keep the piston well lubricated. However, if you notice the sound of the valve changing over time (e.g. slow response time, intermittent operation), or if you can see that the piston is not moving smoothly, it may require a clean and re-lube. Put a rag under the valve to catch any parts that may drop.
