Overview

The 997.1 Carrera and Carrera S came with a plastic T-shaped air distributor that IPD replaces with its patented cast aluminum Y plenum. Choose the 74mm plenum that uses your factory throttle body, or step up to the 82mm Competition plenum for a genuine Porsche GT3 82mm throttle body. IPD's GT Pro dyno testing recorded 29.6 wheel horsepower and 27.1 lb-ft on a stock 3.8L Carrera S.

Features

  • IPD dyno: 19.1 WHP on a 997.1 3.6L and 29.6 WHP on a 3.8L Carrera S
  • 82mm Competition plenum offered with factory airbox hose or aftermarket intake coupler
  • 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
  • Replaces the factory plastic air distributor
  • Gains are strongest in the midrange, where street cars spend the most time

What's Included

  • IPD cast aluminum plenum
  • Silicone hose to fit the factory airbox (Factory Airbox Hose versions)
  • Silicone reducer coupler for aftermarket intake systems (Aftermarket Intake Coupler versions)
  • Genuine Porsche throttle body when the throttle body add-on is selected

Fitment Notes

Choose the plenum that matches your engine. Competition plenums need a GT3 82mm throttle body, offered as an add-on. Power gains are fully realized once the DME completes its adaptation after several full-throttle runs.
