Charge air cooler.
Charge air coolers, often called intercoolers, are heat exchangers that cool the compressed intake air from the turbocharger before it enters the engine’s intake manifold. Turbos heat incoming air during compression; cooling that air increases density and oxygen content, which improves combustion efficiency, power output and reduces the risk of detonation. These coolers also help maintain consistent performance under load by managing intake temperatures.

These coolers are specified for Porsche Cayenne (9YA) models equipped with the 3.0 L turbocharged engine from approximately 2019 onward. They are positioned left and right in the charge-air circuit and are sold individually.

Applications
•  Turbo system service: Replace damaged, cracked, or leaking charge air coolers due to wear or debris impact.
•  Performance restoration: Restore intake charge cooling efficiency after boost system repairs.
•  Diagnostics repair: Address symptoms such as reduced power, increased intake temps, or boost leaks

The charge air cooler cools the turbocharged intake air before it enters the engine’s combustion chambers. By reducing intake air temperature:
•  Air becomes denser, carrying more oxygen
•  Combustion becomes more efficient
•  Power and torque output is more consistent
•  Risk of detonation (engine knock) is reduced
•  Turbocharger spool-up can become more responsive

A failing or inefficient charge air cooler can cause higher intake air temperatures, reduced power output, inconsistent boost delivery, increased engine knock risk, and poorer fuel economy. Damaged or leaking intercoolers also encourage intake pressure loss, reducing performance and drivability. Installing an OE Match charge air cooler restores optimized charge-air cooling, helping the engine produce power consistently, run cooler, and meet emissions expectations.

When to replace.  Replace the charge air cooler when you observe any of the following:
•  Noticeable power loss or inconsistent boost pressure
•  Heat-soak symptoms under sustained load or hot weather
•  Visible external damage, bent core tubes, or leaking seams
•  Oily residue inside or outside the cooler (sign of turbocharger oil contamination)
•  During turbocharger service, intake system overhaul, or front-end repair.
