IPD Boxster/Cayman (2.9) DFI Intake Plenum

The all new specifically designed IPD 2.9L DFI Boxster/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._x000B__x000B_The superior design of the DFI IPD Plenum provides additional horsepower. 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 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._x000B__x000B_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.
