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.
