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 

Diagram Ref No 1 (LEFT) And 2 (RIGHT)

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.

About Inter Coolers

Porsche Inter Coolers

At Design911, we supply a wide range of inter coolers for Porsche models, helping you maintain, personalise and enjoy your car.

Why do Porsche Inter Coolers matter?

Inter Coolers affect how efficiently the engine in your Porsche runs, especially on turbocharged models. Over time they can suffer from leaks, corrosion and reduced efficiency, or simply no longer be suitable once you start tuning the engine. Replacing tired or undersized intercoolers helps your Porsche stay reliable, consistent and enjoyable to drive, particularly under heavy load.

  • Keep your Porsche looking smart rather than tired or neglected
  • Help protect the surrounding area from dirt and corrosion where relevant
  • Reduce minor niggles such as looseness, rattles or mismatched parts
  • Support long-term enjoyment, pride of ownership and potential resale value

When should you review or replace your Porsche inter coolers?

Checking inter coolers regularly helps you spot wear, damage or age-related deterioration before it affects comfort, refinement or leads to more expensive repairs later on.

  • Existing parts are worn, cracked, scuffed, faded, corroded or missing
  • You notice looseness, vibration or an untidy appearance around the area they sit in
  • You have had related work carried out and want everything to look and feel consistent
  • You want the car to feel smarter and better cared for in daily use or before resale

If any of these apply, it is a good time to review your inter coolers and replace anything that is past its best, so your Porsche stays dependable and enjoyable to drive.
