Agency Power has just given Porsche 996TT owners another way to get an easy 25 bolt-on horsepower with this new 84mm race 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. Agency Power has chosen to use a 84mm Porsche throttle body which improves the top end power over the already great 78mm Agency Power throttle body kit. The T shape plenum features all the necessary vacuum and breather hose ports as stock for a true bolt on application. Each plenum features a CNC machined throttle body flange that includes the necessary recessed gasket for a sealed fit. The complete T plenum is TIG welded and then powdercoated gloss black inside and out for a smooth and stealth finish.
This kit includes both the plenum and Porsche OEM throttle body to be used on all Porsche 996 Turbo, X50, or GT2 from 2001-2005.
Note: The Use of This Race Plenum and Throttle Body Requires Custom ECU Tuning.
