OE Match expansion valve is a replacement for the original Porsche part, designed for Porsche 928, 964 and 993 models. It regulates the flow of refrigerant into the evaporator, ensuring the correct pressure balance for efficient cooling and reliable performance.
Fits:
Porsche 928 1982-95 M570 / M573
Porsche 964 1989-94 M573
Porsche 993 1995-98 M573
* M570 - Cars with air conditioner with improved efficiency
* M573 - Cars with standard air conditioner

What this product does:
• Controls refrigerant flow between condenser and evaporator
• Maintains stable pressure for consistent cabin cooling
• Prevents evaporator freeze-up and reduces compressor strain
Location: Installed in the A/C system, between the condenser and evaporator
A worn or clogged expansion valve can cause weak cooling, fluctuating cabin temperatures, or excess strain on the compressor. Replacing expansion valve restores proper cooling efficiency, protects the A/C system, and ensures long-lasting comfort in your Porsche.

Air conditioning evaporators and expansion valves regulate refrigerant flow and heat transfer to keep Porsche cabins comfortable. OEMatch offers replacement evaporators and valves prepared for application-specific fit and refrigerant control, suitable for servicing, restoration and repair where reliable cabin cooling is required.
Available Types
- Evaporator core
- Expansion valve
Understanding OEMatch Air con evaporators & expansion valves
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original air con evaporators & expansion valves.
OE (Original Equipment) refers to parts matching original specifications for the air con evaporators & expansion valves and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM air con evaporators & expansion valves engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
OEMatch supplies a wide range of Porsche parts, cataloguing over 4,000 individual part numbers and more than 8,700 cross-references and continuing to expand its product lines to support maintenance and restoration across Porsche generations.
Benefits Include
- Restores consistent cabin cooling and comfort
- Maintains correct refrigerant pressure and system efficiency
- Helps protect the compressor by reducing contamination and ice formation
Why Air con evaporators & expansion valves Wear and Fail
- Corrosion or cracking of the evaporator core
- Blockage or sticking in the expansion valve from debris
- Moisture contamination or refrigerant leaks reducing cooling capacity
The Importance of Replacing with OEMatch Air con evaporators & expansion valves
Replacing worn evaporators and expansion valves prevents refrigerant loss, internal contamination and compressor strain. For Porsche models, renewing these parts during A/C service preserves system reliability, supports correct pressure control and helps maintain consistent cabin temperature across varied driving conditions.
Advantages
- Direct-fit replacements engineered to match original dimensions and tolerances
- Materials selected for resistance to corrosion and refrigerant exposure
- Suitable for servicing, restoration and preventive maintenance
Support & Advice
These items affect systems that contribute to comfort and the protection of mechanical components. Installation should be carried out by a qualified technician following model-specific procedures and torque settings. If you undertake simple checks, protect paintwork, confirm correct fittings and recheck fasteners after initial use.
