Porsche Performance Intake Plenum - IPD 87474

All Performance Plenums include a new throttle body gasket.

The revolutionary and patented design of the IPD Porsche Plenums improve intake air flow by replacing the factory plastic "T" style design with a more efficient, cast aluminum "Y" design. This innovative “Y” diversion area of the IPD Plenums split and channel intake air flow reducing air flow turbulence and increasing air flow velocity. This superior and proven design ultimately results in considerable power gains throughout both horsepower and torque curves. Performance is also enhanced with our uniquely dimpled interior surfaces which create improved boundary layers further optimizing intake air flow characteristics.

The all new specifically designed IPD DFI Boxster/Cayman 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.
