CSF 964 573 901 00 OEM+ Performance A/C Evaporator for Porsche 964/993

The CSF 964 573 901 00 is a high-performance OEM+ replacement A/C evaporator designed specifically for Porsche 964 and 993 models. This modern evaporator core addresses common issues found in aging factory units, including corrosion, oxidation buildup, and reduced cooling efficiency with R134a refrigerant conversions.

Key Features:

• Cross-flow parallel dual core design with super-high pressure 26mm 12-channel microtubes for optimal refrigerant flow and maximum surface area contact
• 24 total rows of cooling tubes paired with 25 rows of 8mm tall multi-louvered fins for superior heat exchange
• Anti-corrosive finish eliminates white flakes and dust particles caused by oxidation in OEM units
• Optimized for R134a refrigerant, providing approximately 2x better performance than new OEM evaporators
• OEM-style inlet and outlet connections for direct bolt-in fitment
• Includes mounting hardware, O-rings, and bracket for complete installation

This evaporator replaces Porsche OEM part numbers 964-573-901-00 and 964-573-013-00, and cross-references to Behr AE 45 000P. The improved seal design provides better airflow over the evaporator core compared to factory and aftermarket alternatives, resulting in enhanced cabin cooling performance. A cost-effective upgrade that delivers modern cooling technology for classic air-cooled Porsches.
