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.

• 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.
