IPD Intake Plenum for Porsche 997.2 911 Carrera S (3.8L)

Porsche’s DFI (Direct Fuel Injection) intake was a completely redesigned intake system developed to deliver improved performance, fuel consumption and lower emissions by optimizing the air fuel mixture directly inside the combustion chamber.

The DFI Porsche engine package is a finely-tuned performance machine and additional power has proved difficult to find. The unique design of Porsche’s new DFI intake system posed challenging tuning hurdles but once again IPD developed a design that out-performs the factory intake system without compromising reliability and drive-ability.

This innovative and revolutionary IPD DFI Intake Plenum employs the patented “Y” design as well as an enlarged plenum area that allows for improved intake air speed and velocity resulting in increased performance.

The all new specifically designed IPD 3.8L DFI intake Plenum is a direct bolt-on upgrade that replaces the factory air intake distributor and utilizes all pre-existing factory hardware and throttle body.

The improved IPD intake design allows for smoother, less turbulent and more efficient air flow resulting in impressive power and torque gains for Porsche driving enthusiasts.

The superior design of the DFI IPD Plenum provides an additional 15 HP at the wheels. Unlike previous naturally aspirated IPD plenums that delivered stronger gains in the mid range, the new IPD DFI Plenums deliver a similar shaped power curve as the factory but is considerably stronger from the mid-RPMs to redline without any loses in power down low.

Installation of the IPD 3.8L DFI Plenum is relatively straight forward and can be installed by mechanically inclined DIY customers, though IPD strongly recommends installation be performed by a trained and qualified Porsche technician.
