Porsche’s new DFI (Direct Fuel Injection) intake is a totally and completely redesigned intake system developed to deliver improved performance, fuel consumption and 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 very 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 performance increases without any loses in power.

The all new specifically designed IPD 3.6L DFI intake Plenum is a direct bolt-on upgrade that replaces the factory air distributor and utilizes all pre-existing factory hardware including the OE factory throttle body.

The improved IPD intake design creates increased air velocity and air speed resulting in impressive power and torque gains for Porsche driving enthusiast.

The superior design of the DFI IPD Plenum provides an additional 14 horsepower 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 are considerably stronger from the mid range to redline without any power loses down low.

Installation of the new IPD 3.6L DFI Plenum is relatively straight forward and can be installed by mechanically inclined DIY customers although IPD strongly recommends installation be performed by a trained and qualified Porsche technician.

In fuel injected engines, the throttle body is the part of the air intake system that controls the amount of air flowing into the engine, in response to driver accelerator pedal input in the main. The throttle body is usually located between the air filter box and the intake manifold, and it is usually attached to, or near, the mass airflow sensor.

The largest piece inside the throttle body is the throttle plate, which is a butterfly valve that regulates the airflow. Have a larger diameter throttle body produces more air flow with equals more power. The upgrades should be used in conjunction with the competition plenums.

This is a 82mm Thottle body.
