The Cayenne turbo / GTS 4.0ltr Intercoolers have been meticulously designed and engineered to fit exactly like the OEM units they replace. Utilising all factory mounting points, the installation is straightforward with a “drop-in fit” design. No cutting or modifications are required and there is no need for aftermarket shrouds or hoses. All mating OEM components can be reused and reinstalled.

The Thermal Dispersion Black finish is used to aid further the cooling efficiency of these Intercoolers and they are then sent to a special aerospace company where this special ceramic coating is applied. This unique coating rapidly disperses heat away from the intercoolers at an increased rate of about 15% compared to non-coated parts. In addition, this special coating gives the intercoolers a durable OEM stealth look behind the open front bumper air inlets.

CSF has integrated the charge pipe into the design of the top end tank with an aluminum welded pipe replacing the factory bolt-on plastic part which is sealed with an inner O-Ring. It has been stated that the OEM O-Rings may be a factory design flaw as these can fail. This failure causes boost leaks and triggers a check engine light which is quite surprising on such a new vehicle. These O-Rings have been known to already started showing signs of failure with only a few thousand miles on the odometer.

As with CSF’s other products the new Cayenne turbo / GTS Intercoolers feature 100% TIG-welded machined billet aluminum end tanks. This is a very important upgrade compared to the OEM crimped plastic composite end tanks and this feature is not only aesthetically pleasing, but is also stronger offering longevity and durability on high-performance vehicles. The CNC machined billet end tanks are ready to withstand increased boost pressures from bolt-on modifications, higher performance tunes, as well as upgraded turbochargers.

Additional center coolant radiator
The Porsche Genuine OE Additional Center Coolant Radiator (PAB145804) is a specific auxiliary cooling component designed to manage excess heat in hybrid-assisted Cayenne 9YA models. It enhances the ability of the cooling system to regulate coolant temperature during heavy engine load or hybrid system operation - contributing to efficient engine performance and longevity through improved thermal management.

Fits:
Porsche 9YA (E3) Cayenne 3.0L  / 4.0L Hybrid  2018 - 2024
Porsche 9YA.2 (E3 PA) Cayenne 3.0L Hybrid 2023 >>

Diagram ref no 1


This additional center coolant radiator functions as a supplementary heat exchanger in the engine’s cooling system. It helps dissipate excess heat from the engine coolant, reducing overall operating temperature and relieving load on the primary radiator - particularly under higher thermal loads seen in hybrid-assisted or high-performance operation. By improving coolant temperature control, it supports optimal combustion efficiency, long-term durability, and consistent engine performance.

Applications
•  Cooling system repair: Replace a damaged or failed auxiliary radiator component
•  Performance reliability: Add or restore cooling capacity to support hybrid engine thermal loads
•  Factory-standard restoration: Use when rebuilding or fully servicing cooling circuits
•  Preventative maintenance: Install as part of coolant system servicing for consistent temperature control

Fitment / Position on Car
•  Installed on: Engine bay, mounted centrally as part of the coolant heat-exchange system
•  Location: Integrated with front cooling network alongside main radiator cores and intercoolers
•  Connection: Works within the standard coolant piping and hose routing for the Cayenne 9YA hybrid platform

Modern performance and hybrid engines, such as those found in the Cayenne 9YA, generate additional heat due to electric motor assist, turbocharging, and high output demands. An auxiliary radiator increases total cooling surface area, helping prevent overheating, reduce thermal stress on primary components, and maintain consistent performance both in everyday driving and demanding conditions. Choosing a genuine Porsche OE cooling radiator means getting the exact specification, durability, and fitment that Porsche engineers designed for your vehicle’s thermal system

Diagram ref no 1

The additional centre coolant radiator increases the total heat rejection capacity of the cooling system. By providing supplementary heat dissipation ahead of or in conjunction with the main radiator, it helps:
• Maintain consistent operating temperatures under heavy load or high ambient heat
•  Improve thermal stability for engine and hybrid components
•  Reduce strain on the primary radiator and cooling fans
•  Support extended performance driving or high-duty cycles

An inefficient or failing additional radiator can reduce the cooling system’s ability to control engine temperature, leading to overheating, reduced performance, and increased stress on the main radiator. On hybrid models, inadequate thermal management can also impact electrified components. Replacing a compromised unit with an OE Match radiator restores correct cooling capacity and helps maintain performance, reliability, and long-term engine health.

When to replace:
•  Visible damage, bent fins, or leaks
•  Coolant stains or corrosion on the radiator cores
•  Overheating or rising temperature gauges
•  After front-end impact/collision damage
•  During complete cooling system overhaul

Product Information
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.

Fits:

Porsche 9YA.2 Cayenne V6 3.0L 2023 >>

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

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

Intercoolers operate under high temperature and pressure. Using genuine Porsche OE coolers ensures the correct core density, fin design, and pressure handling, which helps maintain engine efficiency, boost response, and power delivery.

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.
