Pressure Pipe.
The Genuine Porsche Pressure Pipe 95511004650 is a replacement charge-air pipe used within the turbocharged intake system of the Porsche Cayenne 955 Turbo and Turbo S.
Fits:
Diagram Ref No 8
Located within the pressurised section of the intake system, the pipe forms part of the connection between the intercooler system and the engine intake.
After the turbochargers compress the incoming air, the air passes through the charge-air coolers before continuing through the pressure-pipe system towards the engine.
This component helps collect and route that compressed air while maintaining the sealed intake path required for correct turbocharger boost pressure.
Because it operates on the pressurised side of the intake system, any crack, split, damaged sealing surface or loose connection can allow boost pressure to escape.
A boost leak can result in reduced engine performance, slower turbo response, hissing noises, fault codes and inconsistent power delivery.
Replacing a damaged pressure pipe helps restore the sealed charge-air system and allows the turbocharged engine to operate at the boost pressure intended by Porsche.
What This Product Does:
The Pressure Pipe forms part of the turbocharged engine's charge-air delivery system.
Its primary functions are to:
- Carry compressed air through the intake system.
- Connect the intercooler/charge-air system to the engine intake.
- Maintain boost pressure between the turbochargers and engine.
- Provide a sealed pathway for pressurised intake air.
- Support correct boost-pressure measurement.
- Help maintain consistent turbocharger response.
- Support correct engine-management calculations.
- Reduce pressure loss within the charge-air system.
- Replace a cracked, leaking or damaged original pressure pipe.
Symptoms Of Wear Or Failure:
Possible symptoms include:
- Loss of engine power.
- Reduced turbocharger boost.
- Slower acceleration.
- Increased turbo lag.
- Hissing under acceleration.
- Whooshing from the engine bay.
- Boost-pressure warning or fault codes.
- Check-engine light.
- Inconsistent power delivery.
- Engine entering reduced-power mode.
- Visible cracks in the pipe.
- Damaged pipe connections.
- Oil mist around a leaking charge-air joint.
- Loose boost-pressure sensor.
- Damaged sealing O-ring.
Why Replacement Matters:
Replacing a leaking or damaged Pressure Pipe helps restore:
- Correct charge-air sealing.
- Target boost pressure.
- Engine power.
- Turbocharger response.
- Consistent acceleration.
- Correct boost-pressure sensor operation.
- Engine-management stability.
- Reliable turbocharged intake operation.

Air Inlet Hoses, Pipes & Sleeves – Durable Intake Components for Porsche Performance
Air inlet hoses, pipes, and sleeves are essential components of your Porsche’s intake system, connecting the air filter housing, throttle body, turbocharger, and intercooler. They ensure a smooth and sealed flow of air into the engine, supporting efficient combustion, responsive acceleration, and consistent performance.
At Design911, we supply a full range of genuine and high-quality air inlet hoses, pipes, and sleeves for numerous Porsche models that include 911, Boxster, Cayman, Cayenne, Macan, and Panamera models. Each component is engineered for precision fitment, heat resistance, and airflow stability — helping your Porsche deliver the performance and reliability it’s known for.
What Do Air Inlet Hoses, Pipes & Sleeves Do?
These components channel filtered air through the intake
system to the engine’s combustion chambers. Their main functions include:
- Maintaining
airtight airflow between intake components.
- Reducing
turbulence and air loss for improved throttle response.
- Supporting
optimal air pressure for turbocharged and naturally aspirated engines.
- Protecting against contaminants that can reduce performance or cause engine wear.
In turbocharged Porsche models, these parts also help manage boost pressure, making them crucial to both efficiency and power delivery.
Why Do Air Inlet Hoses, Pipes & Sleeves Fail?
Due to their constant exposure to heat, vibration, and
engine movement, air inlet components can deteriorate over time. Common causes
of failure include:
- Cracking
or splitting from heat cycles and material fatigue.
- Oil
or fuel vapor contamination softening the rubber or plastic.
- Loose
or damaged clamps causing vacuum or boost leaks.
- Age-related
hardening leading to brittle connections.
- Excessive boost pressure stressing the hose in performance applications.
Symptoms of failure include hissing or whistling noises, loss of boost pressure, poor throttle response, rough idling, or a check engine light caused by airflow irregularities.
Why Replace Worn Air Inlet Components?
A leaking or damaged inlet hose can cause unmetered air to enter the engine, resulting in incorrect fuel-air ratios, poor performance, or even turbocharger strain. Replacing worn or cracked hoses and pipes ensures proper airflow, efficient combustion, and reliable performance.
Benefits of replacement include:
- Restored air pressure and engine response.
- Improved turbo efficiency and power delivery.
- Enhanced fuel economy and reduced emissions.
- Long-term reliability with manufacturer-quality materials.
All hoses, pipes, and sleeves available at Design911 are crafted from high-temperature silicone, reinforced rubber, or aluminium alloys for superior sealing, flexibility, and strength — ensuring dependable performance under demanding conditions.
