The 997S IPD Plenum provide power increases throughout the entire power band. 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 liter IPD Plenum also allows for a 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 occurs 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.
