Performance Plenum

The 987.2 Competition 82mm IPD Plenum requires the additional purchase of the 997 GT3 82mm Throttle Body



The IPD 987.2 Boxster "Competition" Plenum was designed to meet the needs of the most demanding Boxster S enthusiasts. The "Competition" Plenums is internally larger and specifically designed to utilized the larger 82mm 997 GT3 throttle body. This new 987.2 Competition Plenum follows in the foot steps of the very successful 987.1 Competition Plenum, which has proven itself to be the absolute single best performance mod that can be installed on any 987.1. The combination of the patented IPD "Y" designed Plenum and Porsche's largest TB yield great performance gains that can be seen and felt throughout the entire power band.

The "Competition" version was designed and developed to work with Boxster S's equipped with high quality high-flow aftermarket cat-back exhausts. The addition of headers and high-flow cats will only further compliment the dramatic increases with intake air flow delivered by the IPD Plenum.

Performance gains take place throughout both horsepower and torque curves but are most realized through the mid-range and well into peak power range. This system develops up to 20+ HP on Boxster already equipped with aftermarket cat-back exhausts. Once installed, the 987.2 Boxster Competition Plenum will truly transform your Porsche Boxster driving experience.

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 air velocity resulting in performance increases without any power loses.

The all new specifically designed IPD 3.4L DFI Cayman/Boxster Plenum is a direct bolt-on upgrade that replaces the factory plenum and utilizes all pre-existing factory hardware including the OE factory throttle body.

The improved IPD intake design allows for smoother, less turbulent and more efficient air flow with higher velocity air intake speed creating impressive power and torque gains.

The superior design of the DFI IPD Plenum provides an additional 12-14 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.

Power output in the lower rev range follows the Porsche factory output, with NO loses. Power and torque are realized in the midrange and continue to climb above factory power outputs all the way up to redline.

Installation of the new IPD 3.4L 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.

Throttle Body 74mm for Porsche.



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 74mm Throttle body.
