Information
Air Conditioner Heat Exchanger.
This genuine Porsche Heater Matrix (Part No. 95557207001) - also referred to as the heater core, heat exchanger, or air conditioner heat exchanger - is an original-equipment component engineered to Porsche’s precise factory standards. It is specifically designed for Porsche Cayenne (955 / 957 / 958) models equipped with the 4-zone climate control system (Option Code: 9AH), where multiple independent heating and cooling zones require an enhanced internal heat exchange unit.
Fits:
For cars with 4-zone air conditioning system (option code: 9AH)
Porsche 955 Cayenne 2003 - 2006
Porsche 957 Cayenne 2007 - 2010
Porsche 958 Cayenne 2011 - 2018
Diagram ref no 13
The heater matrix is a critical part of the vehicle’s climate control system, responsible for transferring engine coolant heat into the cabin’s ventilation air. Coolant flows through the heater core’s internal tubes, and as air passes over the external surfaces, heat is transferred into the cabin. In a 4-zone air conditioning system, this component supports precise temperature control for multiple separate climate zones, ensuring consistent comfort for front and rear passengers.
In vehicles with Option Code 9AH, the system uses an advanced HVAC architecture requiring a specific heater matrix capable of handling higher air volumes and distinct distribution paths.
Fitment / Position on Car
• Installed in: HVAC housing behind the dashboard
• Location: Integrated into the climate control module where air streams from the blower fan pass through before distribution
• Interface: Works with coolant inlet/outlet hoses, blend doors, actuators, and air plenums to channel conditioned air to multiple zones
A failing heater core can lead to a range of issues - from reduced cabin heating to coolant leaks inside the vehicle, foggy windows, and even engine overheating if coolant loss is significant. Using a genuine Porsche OE heater matrix ensures the correct core resistance, flow rate, and materials engineered to work with Porsche’s advanced 4-zone HVAC system, delivering dependable warmth and climate control performance consistent with factory intent.

Information
Air Conditioner Heat Exchanger.
This MAHLE heater matrix is a premium aftermarket replacement part engineered to match the performance and fit of the Porsche OEM heater core / heat exchanger. This component is a key part of the heating and air conditioning system in Porsche Cayenne 955, 957, and 958 models equipped with the 4-zone air conditioning system (option code 9AH).
Fits:
For cars with 4-zone air conditioning system (option code: 9AH)
Porsche 955 Cayenne 2003 - 2006
Porsche 957 Cayenne 2007 - 2010
Porsche 958 Cayenne 2011 - 2018
Diagram ref no 13
The heater matrix (often referred to as a heater core or heat exchanger) functions like a small radiator located inside the vehicle’s climate control unit. It transfers heat from the engine’s coolant into the cabin airflow. When hot coolant flows through the core’s tubes and fins, air blown across the matrix by the blower motor warms up before entering the passenger compartments, providing comfortable cabin heating even in cold conditions.
Designed and manufactured to strict MAHLE quality standards, this heater matrix delivers reliable heat transfer, long service life, and consistent HVAC performance. It restores proper cabin heating and overall climate control performance when the original OE heater core has failed, become clogged, or begun to leak.
Fitment / Position on Car
• Installed in: HVAC housing behind the dashboard
• Location: Integrated into the climate control module where air streams from the blower fan pass through before distribution
• Interface: Works with coolant inlet/outlet hoses, blend doors, actuators, and air plenums to channel conditioned air to multiple zones

9AH - 4-Zone Air Conditioning System
Diagram Ref No 13
Manufactured from lightweight, high-efficiency aluminium with precision-brazed tubes and densely packed cooling fins, the heat exchanger is engineered to maximise thermal efficiency while withstanding continual temperature fluctuations, refrigerant pressure and long-term use. Designed for direct OE-style installation, it integrates seamlessly with the original heating, ventilation and air conditioning (HVAC) system, restoring factory cooling performance and cabin comfort.
What This Product Does:
- Absorbs heat from the cabin air.
- Cools the air before it enters the passenger compartment.
- Supports efficient operation of the air conditioning system.
- Allows refrigerant to absorb heat and circulate through the system.
- Helps reduce cabin humidity during air conditioning operation.
- Maintains consistent climate control performance.
- Restores factory air conditioning efficiency.
- Forms an essential part of the vehicle's HVAC system.
Symptoms Of Wear Or Failure:
- Weak or ineffective air conditioning performance.
- Warm air blowing from the dashboard vents.
- Refrigerant leaks within the HVAC system.
- Reduced cooling efficiency.
- Unpleasant odours from the ventilation system.
- Moisture or condensation inside the cabin.
- Air conditioning system pressure faults.
- Loss of refrigerant requiring repeated recharging.
- Hissing sounds from the HVAC housing caused by refrigerant leakage.
- Air conditioning system failing to cool correctly.
Why Replacement Matters:
- The air conditioner heat exchanger operates continuously whenever the air conditioning system is in use and is exposed to constant temperature changes, moisture, refrigerant pressure and airflow. Over time, corrosion, contamination or internal deterioration can cause refrigerant leaks or reduce the unit's cooling efficiency.
- A faulty heat exchanger can significantly reduce the effectiveness of the air conditioning system, resulting in poor cabin cooling, increased humidity and loss of refrigerant. Continued operation with a leaking evaporator can place additional strain on the compressor and other air conditioning components, leading to more expensive repairs.
- Replacing a worn or damaged air conditioner heat exchanger restores the cooling efficiency and reliability of the climate control system. The OE Match Air Conditioner Heat Exchanger is manufactured to OE standards using premium-quality materials, providing factory-style fitment, excellent thermal performance and long-lasting durability to maintain the comfort and refinement expected from your Porsche.
