Make a selection AP9972TT102 With the success of our ypipe kit on the 996tt and 997tt, we did a hybrid and built this new part to work with the OEM intake on the 997.2 turbo.

Our ypipe kit has smooth mandrel 3inch bends from a 4inch collector that goes to the throttlebody. For fitment reasons, we then neck down to 2.25inches to fit on the stock boost hoses.

Make a selection AP996TT105 Agency power has just given Porsche 996tt owners another way to get an easy 20 bolt-on horsepower with this new big mouth plenum and throttle body kit. agency power set out to engineer and design a plenum that was functional, did not require additional tuning, and simply. Made power! the plenum is 6061 aluminum that retains the same shape as the factory t pipe. the reason to keep a standard t shape is that the engine works off of pulses. just like how Porsche designed, agency power kept this design and simply improved the restriction, the throttle body. the factory throttle body inlet size is 76mm that then jumps up to a 78mm id plastic plenum.

Make a selection AP997TT105 Adding bolt-on horsepower to the 997 turbo is a continuous quest by many enthusiasts looking for more power. reverting back to old tuning technologies, agency power has developed a larger throttle body and plenum kit for the Porsche 997 turbo to gain added performance. the point of a larger throttle body is to get in more air. The more air you bring in, the more power you make. The 997 turbo's engine intake system works off pulses, so how that air is diverted to either side of the engine is not as important as the volume incoming. General Fitment911 2005-08
