Radiator Intercooler. Porsche 957 Cayenne DIESEL / 958 Cayenne DIESEL  ❭  95814580

Radiator Intercooler.
The OE Match Radiator Intercooler is a high-quality replacement charge air cooling component designed for turbocharged Porsche applications. Engineered to OE specifications for fit, performance and durability, this intercooler reduces the temperature of compressed air generated by the turbocharger before it enters the engine, helping to maximise power output, combustion efficiency and overall engine reliability.

Fits:

• Porsche 957 Cayenne 3.0L Diesel 2007-10
• Porsche 958 Cayenne V6 3.0L Diesel (245Hp) 2010-17

Featuring a precision-manufactured cooling core and durable end tank construction, the intercooler efficiently dissipates heat from the charge air system. By delivering cooler, denser intake air to the engine, it helps maintain consistent boost performance and supports the responsive driving characteristics expected from a Porsche vehicle.  

What This Product Does:

• Cools compressed air from the turbocharger before it enters the engine.
• Increases intake air density for improved combustion efficiency.
• Supports optimum engine power and torque output.
• Helps maintain consistent boost pressure performance.
• Reduces intake air temperatures during demanding driving conditions.
• Improves turbocharger system efficiency.
• Enhances throttle response and engine reliability.
• Contributes to overall engine thermal management.

Symptoms Of Wear Or Failure:

• Reduced engine power and acceleration.
• Loss of turbocharger boost pressure.
• Sluggish throttle response.
• Increased fuel consumption.
• Hissing noises caused by boost leaks.
• Excessive black exhaust smoke under acceleration.
• Engine management warning lights.
• Oil residue around intercooler pipe connections.
• Visible corrosion, impact damage or cracking of the intercooler core.
• Fault codes relating to intake air pressure or boost system performance.

Why Replacement Matters:

• Intercoolers operate under demanding conditions and are continuously exposed to high-pressure intake air, temperature fluctuations, moisture, road debris and environmental contamination. Over time, the cooling core may become damaged, corroded or develop leaks that reduce cooling efficiency and compromise boost pressure retention.
• A failing intercooler can allow compressed air to escape, reducing engine performance and forcing the turbocharger to work harder to achieve target boost levels. Higher intake air temperatures can negatively affect combustion efficiency, fuel economy and engine longevity. Continued operation with a damaged intercooler may place additional strain on the turbocharger and associated intake system components.
• Replacing a worn or damaged intercooler restores efficient charge air cooling, maintains boost pressure integrity and helps preserve engine performance. An OE Match replacement provides factory-style fitment, effective heat dissipation and long-term durability, ensuring your Porsche continues to deliver optimum power, efficiency and reliability.
