Charge air coolers, LEFT & RIGHT. Porsche 9YA Cayenne 3.0L 2018>>  ❭  PAB14580XA

Charge air coolers
often called intercoolers. This OE Match set Charge Air Coolers is a complete left and right intercooler replacement package for the Porsche 9YA Cayenne 3.0L turbocharged models (2018>>). These intercoolers reduce the temperature of compressed air from the turbochargers before it enters the combustion chambers. Cooler air is denser, allowing improved oxygen content, more efficient combustion, and stable power delivery.
SET OF 2

Fits:
Porsche 9YA Cayenne V6 3.0L 2018 - 2024 (PR:T9I)
Porsche 9YA.2 Cayenne V6 3.0L 2023 >>

Diagram ref no 1 (Left) and 2 (Right)

This OE Match SET OF 2 includes both:
• Left Charge Air Cooler – OE ref no PAB145803A
• Right Charge Air Cooler – OE ref no PAB145804A

Each unit is constructed from high-efficiency aluminium cores with precision-formed cooling fins and durable end tanks engineered to withstand boost pressure and thermal cycling. Replacing both sides together ensures balanced airflow, consistent intake temperatures, and optimal turbocharger performance.

Over time, intercoolers can suffer from:
•  Heat-soak efficiency loss
•  Internal contamination (oil mist from turbo system)
•  External fin damage from debris
•  Boost leaks from cracked seams or worn connections

Installing this OE Match pair restores full cooling capacity and ensures consistent intake air temperature across both sides of the engine.
Direct-fit design allows straightforward installation using factory mounting points and original boost hoses.

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.
