Intercooler to Turbocharger Pressure Hose
These intercooler to turbocharger pressure hoses are designed for Porsche 991.1 and 991.2 turbo models and are specific to
cylinders 1–3 (bank 1) and 4-6 (bank 2). They form a critical part of the turbocharged charge air
system, ensuring compressed air is transferred efficiently between the
turbocharger and intercooler.

In high-performance twin-turbo Porsche engines, each bank operates under extreme pressure and temperature. This hose plays a vital role in maintaining boost pressure and ensuring consistent airflow to the engine.
What This Pressure Hose Does
This hose connects the turbocharger to the intercoolers allowing compressed air to be cooled before entering the engine.
It helps:
• Maintain stable boost pressure
• Ensure efficient airflow between turbocharger and intercooler
• Deliver cooled air for optimal combustion
• Support balanced engine performance across both cylinder banks
• Maintain airtight integrity of the charge air system
A failure in this hose can directly affect performance on one side of the engine.
Why Intercooler/Turbo Pressure Hoses Fail
Due to the extreme operating conditions of turbocharged engines, these hoses are subject to wear over time.
Common causes include:
Heat and pressure cycling
Constant exposure to high temperatures and boost pressure weakens materials.
Cracking or splitting
Rubber or reinforced sections can degrade, especially near connectors.
Boost pressure stress
Higher boost levels increase strain on hoses.
Seal and clamp deterioration
Connections can loosen or wear, causing air leaks.
Symptoms of a Failing Pressure Hose
• Loss of boost pressure
• Reduced engine performance or uneven power delivery
• Hissing or air leak noise under acceleration
• Engine warning lights related to boost or airflow imbalance
• Poor throttle response
• Increased fuel consumption
Replacing a faulty hose restores balanced airflow and engine performance.
Why You May Need to Replace This Hose
Restore Balanced Boost Pressure
Ensures consistent performance across both cylinder banks.
Eliminate Boost Leaks
Prevents pressure loss within the turbo system.
Improve Engine Efficiency
Maintains optimal airflow and combustion.
Prevent Further Turbo System Damage
Leaks can cause increased strain on turbochargers and related components.

The Cayenne turbo / GTS 4.0ltr Intercoolers have been meticulously designed and engineered to fit exactly like the OEM units they replace. Utilising all factory mounting points, the installation is straightforward with a “drop-in fit” design. No cutting or modifications are required and there is no need for aftermarket shrouds or hoses. All mating OEM components can be reused and reinstalled.
The Thermal Dispersion Black finish is used to aid further the cooling efficiency of these Intercoolers and they are then sent to a special aerospace company where this special ceramic coating is applied. This unique coating rapidly disperses heat away from the intercoolers at an increased rate of about 15% compared to non-coated parts. In addition, this special coating gives the intercoolers a durable OEM stealth look behind the open front bumper air inlets.
CSF has integrated the charge pipe into the design of the top end tank with an aluminum welded pipe replacing the factory bolt-on plastic part which is sealed with an inner O-Ring. It has been stated that the OEM O-Rings may be a factory design flaw as these can fail. This failure causes boost leaks and triggers a check engine light which is quite surprising on such a new vehicle. These O-Rings have been known to already started showing signs of failure with only a few thousand miles on the odometer.
As with CSF’s other products the new Cayenne turbo / GTS Intercoolers feature 100% TIG-welded machined billet aluminum end tanks. This is a very important upgrade compared to the OEM crimped plastic composite end tanks and this feature is not only aesthetically pleasing, but is also stronger offering longevity and durability on high-performance vehicles. The CNC machined billet end tanks are ready to withstand increased boost pressures from bolt-on modifications, higher performance tunes, as well as upgraded turbochargers.
