Porsche 955 Turbo/Turbo S IPD Intake Plenum

Upgrade your Plenum to the cast aluminum design from IPD, and enjoy the gains that come from ditching the factory plastic “T” style design. The IPD Plenums distribute the air flow more effectively by using a true merge collector and reducing pressure drop at the throttle body inlet.

This innovative “Y” diversion area of the IPD Plenums split and channel intake air flow, reducing air flow turbulence and increasing air flow velocity. This superior design ultimately results in considerable power gains throughout the horsepower (up to 30 hp )and torque (up to 32 ft/lb) curves.
