Porsche 997 Gen 2 Atmospheric Valve Kit



We recommend servicing your valve every 3 years, or 20,000 miles, whichever comes sooner

This is a Atmospheric Valve Kit for the Porsche 997 Gen 2 .

The kit is perfect replacement for the OEM valve, which is prone to failure when the engine has been tuned or had an upgrade to the engine management software, whilst also giving you the incredible sound as you lift off the throttle

Following the resounding success of our direct replacement valves for other OEM applications, we have just completed development and testing of a pair of direct replacement bypass valves specific to the Porsche 997 Gen 2 twin turbo application. These direct replacement units utilise 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 temperature o-rings 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. In addition we supply silicone hoses that are capable of withstanding greater temperatures and pressures, often associated with tuned or track use vehicles.

A choice of either Black or Silver valves are the only option for this kit. Please choose using the options above.
