IPD 987.2 Cayman and Boxster Base 2.9L 74mm IPD Plenum ('09-'12)

987.2 Cayman Base 2.9L 74mm IPD Plenum ('09-'12) | Part #87474-2.9

The specifically designed 987.2 Cayman Non-S 2.9L Cayman Plenum is a direct bolt-on upgrade utilizing all pre-existing factory hardware including factory 74mm 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 IPD Plenum provides additional horsepower. Unlike previous naturally aspirated IPD plenums that delivered stronger gains in the mid range, the new IPD Plenums deliver a similar shaped power curve as the factory but are considerably stronger from the mid range to redline.

Power and torque are realized in the midrange and continue to climb above factory power outputs all the way up to redline without any loses of power down low.

Installation of the IPD 2.9L 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.

Porsche's introduction of their DFI (Direct Fuel Injection) intake was 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 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.
