Works with Factory 74mm Throttle Body

The incredible 997 Porsche Turbo is the most revolutionary and capable Porsche Turbo to ever come out of Germany. The already explosive power can be further increased with the 997 Turbo IPD Intake Plenums.

The patented IPD Plenum design works exceptionally well with all forced induction applications and the 997 Turbo is no exception. Power and torque increases provided by the IPD plenum are impressive and stay over and above all factory power curves from launch to redline. Maximum power increases take place in the midrange where it's most needed and most critical.

Maximum horsepower gains range from 30 to 35 depending on vehicle condition and pre-existing mods. The 997 Turbo plenums deliver smooth and linear power with considerably quicker boost response creating a longer and more desirable power band. The Turbo plenums deliver reliable performance for both street and motorsport applications enhancing the already visceral Porsche Turbo driving experience.

Unlike the 996 Turbo the 997 Turbo requires an “adaptation” period that can be fully realized with either a series of hard pulls on the dyno or 10 to 50 miles of hard driving which of course IPD recommends only be performed on a closed circuit race track.

The 997 Turbo has an extremely sensitive ECU/DME making it prone to external environmental corrections so it is imperative that proper, adequate and consistent cooling be available when you dyno any of the 997 Turbos to get accurate and reliable dyno figures both before and after each test. Installation of all Turbo Plenums is highly recommended to be performed by qualified and trained Porsche technicians.

Turbo customers looking to increase engine power without pushing the motorsport envelope to redline would best benefit from the 74mm IPD Turbo Plenum.

This version of the 997 Turbo plenum utilizes the factory 74mm throttle body and delivers impressive performance gains for both stock and slightly modified Turbos with exhaust and software. Beyond these performance mods we recommend upgrading to the larger 82mm IPD Turbo Plenum.

The 74mm IPD Turbo Plenum is also designed to perform with the higher flowing IPD “Y” Pipe.
