Description

IPD's DFI plenum for the 991.1 Carrera and Carrera S replaces the factory air distributor and keeps the factory throttle body and all existing hardware. Unlike IPD's earlier port-injection plenums, which made their biggest gains in the midrange, the DFI design follows the factory power curve and gets stronger from the midrange to redline. IPD rates it at about 14 wheel horsepower on the 3.4L and 15 on the 3.8L.

Features

  • IPD-rated gains of about 14 WHP (3.4L) and 15 WHP (3.8L)
  • IPD's patented Y-shaped merge in place of the factory T-style air distributor
  • Cast aluminum construction, made in the USA by IPD in Huntington Beach, California
  • Dimpled internal surface designed to keep air moving smoothly through the merge
  • Direct bolt-on that reuses the factory throttle body and hardware
  • Gains build from the midrange to redline while keeping the factory curve shape

What's Included

  • IPD DFI plenum

Specifications

  • Brand: IPD Plenums (Innovative Pro Design)
  • Material: Cast aluminum
  • Made in: USA
  • Part # 91482-3.4: DFI plenum for the 991.1 Carrera 3.4L; reuses the factory throttle body.
  • Part # 91482-3.8: DFI plenum for the 991.1 Carrera S 3.8L; reuses the factory throttle body.

Fitment Notes

Choose the plenum that matches your engine size. Power gains are fully realized once the factory DME completes its adaptation after several full-throttle runs.
