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.
Fits:
- Porsche 991.1 Turbo 3.8L (520 Bhp) 2014-16
- Porsche 991.1 Turbo S 3.8L (560 Bhp) 2014-16

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.
