IPD Intake Plenum for Porsche 991.1 Carrera S/GTS/4S


  • Porsche Carrera S (2011-2015)
  • Porsche Carrera GTS (2014-2016)
  • Porsche Targa 4S (2014-2016)

Like most Carreras, the power output of this Porsche's 3.8L naturally-aspirated engine is controlled to meet a performance target that satisfies mass buyers but not necessarily the dedicated Porsche driving enthusiast. IPD helps scratch the proverbial performance itch for Porsche drivers looking to elevate the already visceral driving experience to the next level.

The 3.8L engine in the 991 Carrera S, GTS, and 4S is relatively unchanged from the previous 997.2 Carrera S, continuing to employ the 82mm throttle body. IPD's new specifically-designed 3.8L DFI Carrera S intake plenum is a direct bolt-on upgrade that replaces the factory air distributor and utilizes all pre-existing factory hardware including that OE factory throttle body.


The improved IPD intake design creates increased air velocity and air speed resulting in impressive power and torque gains of 15 HP and 14 lbs-ft. at the wheels on an otherwise-stock 991 S. As with most IPD plenums, the bulk of the power gains are realized in the mid-range where they are most used and enjoyed. Unlike other mods, though, the IPD Plenum delivers net power gains across the entire rev range.

Installation time is four to five hours and should only be performed by a qualified Porsche technician. Feel free to give us a call at 888-748-7223 with any questions!
