Performance Plenum
The IPD Cayenne Plenum provides power by means of a superior design that increases air speed, boost response and performance. This is achieved with larger inlets and better diversion areas. The cast aluminum construction can also withstand higher pressures and heat levels. The factory plastic intake is very prone to cracking, especially with Cayenne Turbos producing higher boost levels.
The improved design of the IPD Cayenne Turbo Plenum installs easily and delivers additional horsepower that will make your Cayenne Turbo even more menacing.
The new Cayenne Turbo Plenum delivers up to 30 horsepower and 32 foot pounds of torque giving your Cayenne an improved boost in engine power and driving performance.
The superior design of the IPD Cayenne Turbo plenum not only increases power but also improves boost response creating a longer, stronger, more linear and of course more pleasurable power curve.
The 957 Turbo utilizes the factory 76mm throttle body and hardware making installation quick and easy although IPD strongly recommends a qualified Porsche technician perform any Plenum installs.

In fuel injected engines, the throttle body is the part of the air intake system that controls the amount of air flowing into the engine, in response to driver accelerator pedal input in the main. The throttle body is usually located between the air filter box and the intake manifold, and it is usually attached to, or near, the mass airflow sensor.
The largest piece inside the throttle body is the throttle plate, which is a butterfly valve that regulates the airflow. Have a larger diameter throttle body produces more air flow with equals more power. The upgrades should be used in conjunction with the competition plenums.

Performance Plenums – Maximise Airflow, Power & Efficiency for Your Porsche
A performance plenum is a critical upgrade for Porsche enthusiasts looking to improve throttle response, airflow efficiency, and overall engine performance. Sitting between the throttle body and intake runners, the plenum distributes incoming air evenly across all cylinders — ensuring consistent combustion and optimised power delivery.
At Design911, we offer a premium range of performance-engineered plenums designed specifically for Porsche models. Constructed from lightweight aluminium, carbon fibre, or composite materials, these units feature advanced internal flow geometry to reduce turbulence and increase air velocity.
Whether you’re enhancing a classic 911 or tuning a modern Cayman, our high-quality plenums are developed to deliver proven performance gains, sharper throttle response, and a more linear torque curve — perfect for both road and track use.
What Do Performance Plenums Do?
The plenum serves as an air distribution chamber that balances airflow between the cylinders. Upgrading to a performance plenum improves air charge efficiency, resulting in smoother engine breathing and increased power output.
Core Functions:
- Distribute
intake air evenly to all engine cylinders.
- Optimise
airflow dynamics for faster throttle response.
- Increase
air velocity and reduce pressure loss.
- Improve torque and mid-range performance.
- Enhance engine efficiency and fuel-air mixture stability.
A well-designed plenum ensures that every cylinder receives the right amount of air at the right time — unlocking smoother acceleration and more consistent power.
Why Do Plenums Fail or Require Replacement?
Over time, standard plenums can suffer from material fatigue, cracks, or restricted internal passages, all of which impact performance and reliability.
Common Causes of Failure Include:
- Cracks
or leaks from heat cycling and vibration.
- Carbon
build-up restricting airflow.
- Worn
gaskets or seals causing pressure loss.
- Plastic
deformation under extreme boost or temperature.
- Reduced efficiency due to outdated or restrictive design.
Signs of a failing plenum include loss of throttle response, poor fuel economy, uneven idle, or reduced torque. Replacing it with a performance-engineered unit restores full airflow efficiency and reliability.
Why Upgrade to a
Precision-Engineered Performance Plenum?
Upgrading your Porsche’s intake system with a high-performance
plenum enhances power delivery, throttle sharpness, and efficiency —
particularly when combined with a performance air intake and tuning.
Key Benefits:
- Increases horsepower and torque throughout the rev range.
- Delivers faster throttle response and improved drivability.
- Constructed from lightweight, heat-resistant materials.
- Improves airflow balance and reduces pressure drop.
- Direct-fit
compatibility for Porsche 911, Cayman, Boxster, and more.
- Ideal for performance tuning, track driving, and high-output builds.
Replacing restrictive intake components with a performance plenum unlocks your Porsche’s full potential, ensuring stronger mid-range power and greater engine efficiency.
Highlights:
- Performance-engineered plenums for Porsche tuning and upgrades.
- Improves airflow distribution, power delivery, and throttle response.
- Built from aluminium or carbon fibre for strength and weight reduction.
- Direct-fit installation with precision-sealed fittings.
- Perfect for high-performance, racing, or spirited road driving.
- Enhances engine sound and overall responsiveness.
