Charge air cooler by Mahle for Porsche 957 and 958 Cayenne 3.0L Diesel models. It forms part of the turbocharged engine's charge-air cooling system, helping to reduce the temperature of compressed intake air before it enters the engine.
Fits
- Cayenne 957 3.0L Diesel 2007–10
- Cayenne 958 V6 3.0L Diesel (245Hp) 2010–17
What This Product Does
The charge air cooler transfers heat away from compressed intake air. Maintaining a sealed, undamaged cooler and associated pipework supports consistent charge-air flow through the intake system.
Functions
- Cools compressed intake air within the charge-air system.
- Provides a connection point for the relevant pressure hoses and pipes.
- Helps maintain a sealed route for turbocharged intake air.
Technical Details
- Charge air cooler reference 958145803A: left-hand side.
- Charge air cooler reference 958145804A: right-hand side.
- Shown for Cayenne 9PA1 (957) 3.0L Diesel 2007-10.
- Also shown for Cayenne 92A (958) 3.0L Diesel applications, including 2011-18 and 05/2014-18 diagram coverage.
- Related assembly components include pressure hoses, seal rings, hose clamps, retaining springs and pressure pipes.
Symptoms of Fault
- Hissing from the charge-air system.
- Loss of boost or reduced engine response under load.
- Underboost-related fault messages.
- Oil residue around the cooler connections or pipework.
- Visible damage, corrosion or distorted cooling fins.
Why Replacement Matters
A leaking or damaged charge air cooler can allow boosted air to escape and may affect intake-air temperature control. Replacing a faulty unit while checking its seals, hoses, clamps and retaining hardware helps address the complete charge-air connection.
FAQs
- Is this cooler side-specific?
Yes. Diagram reference 958145803A is left-hand, while 958145804A is right-hand. - Should related parts be inspected during replacement?
Inspect the pressure hoses, seal rings, clamps and retaining hardware for wear or damage. - How can a charge-air leak be confirmed?
A suitable pressure test of the charge-air system can help identify leaks in the cooler, hoses and connections.
Check fitment for your specific vehicle, including model, year and engine, before ordering.

This OE Match intercooler is a direct replacement for Porsche part, manufactured to original specifications, it ensures precise fitment and reliable performance within the turbocharged intake system. Installed at the front of the vehicle, the intercooler cools compressed air from the turbochargers before it enters the engine. By reducing intake air temperature, it improves combustion efficiency and supports optimal engine performance.
Fits:
Porsche 957 Cayenne Turbo 4.8L 2007 - 2010
Porsche 958 Cayenne Turbo 4.8L 2011 - 2018

The intercooler lowers the temperature of compressed air from the turbochargers, increasing air density and improving engine efficiency. This results in better power output, improved throttle response, and enhanced reliability.
A properly functioning intercooler is essential for maintaining consistent turbo performance and preventing heat-related power loss.
Function
• Cools compressed intake air from turbochargers
• Improves combustion efficiency and engine performance
• Maintains stable intake air temperatures
• Supports consistent boost pressure and power delivery
This component is critical for performance and engine protection in turbocharged vehicles.
Over time, intercoolers can become clogged, corroded, or develop internal leaks, reducing their cooling efficiency. This can lead to higher intake temperatures, reduced performance, and increased engine stress.
Replacing a worn intercooler restores proper cooling, improves engine efficiency, and ensures reliable turbocharged performance.
When to replace:
• Loss of power or reduced turbo efficiency
• Boost leaks or hissing noises
• Oil contamination inside intercooler
• Visible external damage or corrosion
• Fault codes related to intake temperature or boost pressure
