IPD 987.2 DFI Cayman 2.9L & Boxster IPD Plenum
The all new specifically designed IPD 2.9L DFI 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 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.
