The 997S IPD Plenum provides power increases throughout the entire powerband. Gains of 28 horsepower and 26 foot-pounds of torque are experienced in the midrange with gains of 11 to 12 hp at the peak.
The "Y" design of the 3.8-litre IPD Plenum also allows for more linear power delivery and improved throttle response that elevates the 997 S Carrera driving experience even higher.
Power improvements will be fully realized once the factory DME makes all the necessary “adaptation” requirements which occur after a series of hard pulls on the dyno or full throttle runs (at your local race track of course).
The 997S IPD Plenum is a direct bolt-on replacement and installation is relatively straight forward for mechanically inclined DIY customers although IPD strongly recommends all Plenum installations be performed by a trained and qualified Porsche technician.
