Agency Power has a brand new Blow Off Valve solution for the Porsche 996 Twin Turbo cars. The Porsche like many European cars has a sensitive MAF. Running a 100% vent to atmospheric valve on most stock or mildly tuned vehicles will cause check engine lights and vehicle performance issues. Since the stock Bosch plastic diverter valves leak boost and robs you of power, Agency Power has developed this single Blow Off Valve kit to give you the best boost consistency and sound out t HERE. Having dual diverter valves is not necessary as the F-Hose is straight through so both valves get the pressure equally. The Agency Power Blow Off Valve has an upgrade spring and piston design to handle up to 50psi of boost! The valve has an adjustable top to help set the stiffness of the spring depending on your vehicle setup. Whether you are running .7bar or 1.3bar, the valve can give you optimal boost consistency. In addition to being adjustable, the valve can be setup in 3 different configurations. You can set it up as a full recirculation like a stock valve, full 100% atmospheric for high horsepower race cars, or even 50/50 for street cars wanting that Blow Off Valve sound.
The Valves are made from CNC machined 6061 aluminum with nylon washers and a brass piston to keep movement and air venting for the life of the car. Each body has the Agency Power logo laser engraved on it and the adjuster knob is triangular for easy grip. The single Blow Off Valve kit works on all Porsche 996TT from 01-05 and fits in the stock or aftermarket Agency Power F-Hose. Each kit includes 2 plugs for the factory holes and new worm clamps. Additional plugs or horns can be purchased separately. Valves come in polished, red, or black.
