987.2 DFI Boxster S 3.4L IPD Plenum

The all new specifically designed IPD 3.4L DFI Boxster S 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. Installation of the new IPD 3.4L DFI Boxster S 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.
