Following the resounding success of direct replacement valves for other OEM applications, Forge have just completed development and testing of a pair of direct replacement bypass valves specific to the Porsche 997 twin turbo application.

These direct replacement units utilize full billet aluminum construction and a piston based design that has proved successful throughout our entire range of application specific and universal valve products. Viton brand high temp silicone o-ring are used for sealing of the piston and the valve cap, Mobil1 fully synthetic bearing grease for lubrication of the internals, and a proprietary spring rate is used to handle the widest possible range of boost pressures. 
The low-profile cap incorporates a swiveling center section that allows for 360 rotation of the vacuum nipple for ease of fitment. This also allows for quick disassembly of the valve without requiring removal from the vehicle should servicing of the internals be required.


This is a piston design recirculation valve that is a direct replacement for the original fitment. This valve gives greater longevity than the OEM diaphragm valves but also benefits from its ability to be fitted with different springs when the boost pressure has been increased or the engine has been modified.

Features:

• Low-profile cap
• Swiveling center section that allows for 360 rotation of the vacuum nipple for ease of fitment
• Full billet aluminum construction
• Piston based design
• Viton brand high temp silicone o-ring
• Mobil1 fully synthetic bearing grease for lubrication of the internals
• Proprietary spring rate
