Radiator Intercooler. Porsche 955 Cayenne Turbo 4.5L 2003-06  ❭  95511080402

Radiator Intercooler.
The OE Match Radiator Intercooler is a high-quality replacement charge air cooling component designed to reduce the temperature of compressed air produced by the turbocharger before it enters the engine. Manufactured to OE specifications for fit, performance and durability, this intercooler helps maximise engine efficiency, power output and reliability by delivering cooler, denser air to the combustion chambers.

Fits:

Featuring a precision-engineered cooling core and durable construction, the intercooler efficiently dissipates heat generated during turbocharger operation. By lowering intake air temperatures, it improves combustion efficiency, supports consistent boost pressure and helps maintain optimum engine performance under demanding driving conditions.  

What This Product Does:

• Cools compressed air from the turbocharger before it enters the engine.
• Increases intake air density for more efficient combustion.
• Supports optimum engine power and torque output.
• Helps maintain stable intake air temperatures under load.
• Improves turbocharger system efficiency.
• Enhances throttle response and engine performance.
• Contributes to engine reliability and 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 connections or pipework.
• Visible impact damage, corrosion or cracks in the intercooler core.
• Fault codes relating to boost pressure or intake air system performance.

Why Replacement Matters:

• Intercoolers operate in demanding conditions and are constantly exposed to pressurised intake air, temperature fluctuations, road debris, moisture and environmental contaminants. Over time, the cooling core may become damaged, blocked 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 increasing turbocharger workload. Elevated intake temperatures can negatively affect combustion efficiency, fuel economy and engine reliability. Continued operation with a damaged intercooler may place additional stress on the turbocharger, intake system and engine 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, excellent heat dissipation and long-term durability, ensuring your Porsche continues to deliver the power, efficiency and driving characteristics it was designed to provide.
