Description

For the e-throttle 996 Carrera, IPD makes engine-specific 74mm plenums for the 3.4L, the 3.6L and the X51 Powerkit car, plus an 82mm Competition plenum for owners adding a GT3 82mm throttle body. Each replaces the factory plastic distributor with IPD's dimpled cast aluminum Y. Independent dyno pulls published by IPD show 23 to 28 wheel horsepower gains across the 996 range.

Features

  • IPD-published dyno: 25 WHP on a 3.4L, 24 WHP on a 3.6L and 28.2 WHP on an X51
  • 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

  • Part # 96174-X: 74mm plenum for 996 Carreras with the X51 Powerkit.
  • Part # 96182-RH: 82mm Competition plenum for the 996 3.4L and 3.6L; includes a silicone reducer coupler for aftermarket intake systems; requires a GT3 82mm throttle body.
  • Part # TB0082: Genuine Porsche GT3 82mm throttle body, required for 82mm Competition plenums.

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.
