Porsche 958 / 958.2 Cayenne Turbo IPD Intake Plenum (2011-2018)

The very successful Cayenne was Porsche's solution for driving enthusiast who needed to carry additional passengers and cargo but didn't want to sacrifice driving excitement.

The IPD plenums provide great bolt on power for all late model Porsche applications but they work exceptionally well with all Porsche Turbos models, and the Cayenne Turbo is no exception.

The latest Cayenne Turbo offer from Leipzig comes in the form of a more muscular and capable redesign. The Cayenne hit the gym and dropped 550 pounds and shed some wind resistance with a new aero package. Athletic performance is more agile and faster with almost 500 HP (493 HP) from the Turbo's 4.8 L twin turbo V8. Fortunately Porsche continued to utilize the previous intake from the 957 Cayenne Turbo allowing IPD to continue to provide customers with substantial power and torque gains that will give the new model over 525 horsepower at the wheels.

The IPD Cayenne Turbo plenum has an accentuated diversion area and larger inlet openings that increase intake air speed while improving intake air turbulence. This more efficient design provides substantial power increases of an additional 30+ horsepower and 32+ foot pounds of torque. The Cayenne Turbo Plenum performance gains are throughout the entire power curve and not only provide additional power that can be felt in the "seat of your pants" but deliver this power sooner with improve boost response.

The factory plastic intakes are also prone to cracking, especially with Cayenne Turbos producing higher boost levels. The IPD Plenum will not crack and will handle the highest of boost levels.

The IPD Plenum utilizes all the factory hardware including the OE 76mm throttle body. The only thing more impressive than the substantial power gains provided by the IPD Cayenne Turbo plenum is how easy they install.

1. Superior and more efficient design over the factory intake.
   The IPD Plenums are products of efficiency that simply improve intake air flow and increase air velocity. The “Y” shape design and dimpled interior surface make air flow more laminar (less turbulent) dramatically improving power and torque across the entire RPM band. Smoother more optimized intake air flow will improve the performance of any engines. The more efficiently an engine breaths, the more efficiently it produces power. 
2. Deliver impressive power gains regardless of modifications.
   The superior design of the IPD Plenums optimize flow while increasing air velocity. Period! This applies to any Porsche engine, producing any level of power. The patented “Y” design delivers impressive performance gains for both bone-stock and highly modified Porsches. The more efficient design of the IPD Plenum will always outperform the factory air distributor. The factory intake will become even more detrimental to performance as your increase the power and torque outputs. The bigger the power, the better the IPD Plenum performs.
   
   
3. Produce substantial gains for both turbo and NA applications.
   The Plenums always deliver considerable gains on both turbo AND naturally aspirated engines. It's a fact that the Turbo Plenums do produce more power than the NA Plenums. But the Turbo engines also produce more power. The fact is that the percentage gains of the different Plenum applications are actually almost identical, around 8-10% depending on the specific model. 
   
   
4. Do not require an ECU flash and will not cause a CEL.
   IPD Plenums should never cause a CEL or require an ECU Flash. If a Plenum is installed correctly there should be no fault codes or running issues, only solid performance gains across the entire RPM band. The only issue that could possibly arise is the need for a new MAF sensor if you already have a degraded sensor or perform a TB adaptation. There is absolutely no need to re-flash your ECU after installing an IPD Plenum, Period! Although any reputable Porsche tuner could further optimize an ECU program to achieve even greater performance gains with the Plenum installed.
   
   
5. Aluminum Plenums run cooler and don't suffer from heat soak.
   The Aluminum Plenums do NOT experience heat soak under driving or racing conditions. It is true that aluminum has a higher thermal conductivity than plastic. In fact, aluminum is 650 times more thermally conductive than plastic and has a specific heat capacity that is 550 times higher than plastic. This means the aluminum Plenum actually spreads the energy it's exposed to 656 times faster than the plastic and can store more than 550 times the amount of energy per unit mass. Bottom line, aluminum can absorb more heat than plastic, but it also takes considerably more energy to heat up and it's losing that energy way faster than the aluminum allowing the IPD Plenum to remain cooler from outside ambient air under driving conditions, ultimately improving engine performance over plastic. Plus, why would Porsche utilize aluminum intakes on GT3's, GT2's, Cup Cars and Cup R's?
   

NOTE: If you are upgrading your throttle body along with the IPD Plenum, you may need to visit a dealership to have them perform a manual throttle body adaptation process. Some customers have reported that installing the throttle body and plenum while the battery is disconnected results in the car performing an adaptation check once the battery is reconnected, alleviating the need to visit a dealership. However, Fabspeed recommends having the adaptation performed at a certified dealership for optimal results. If you need a recommendation for a dealership in your area, please contact us.

Please confirm if your vehicle is equipped with the factory Sound Imposer Package. This is easily identified by raising your hood and inspecting the front center of the engine compartment.

• Base Plenum fits (Non-Sound Imposers) Factory Intake. Look for black plastic ribbed construction
  
• Sound Imposer plugs required (Sound Imposer Equipped) Factory Intake. Look for aluminum construction
