CSF 8368 addresses a fundamental limitation of the original factory evaporator: the OEM serpentine-tube design was engineered around R12 refrigerant, and its cooling efficiency drops significantly when converted to modern R134a. CSF solved this with a parallel dual-core design featuring super-high pressure 26mm 12-channel microtubes and multi-louvered fins, delivering substantially more cooling surface area than the OEM unit while actually measuring 15mm slimmer at 52mm total core thickness versus the factory 67mm. The dual-core layout packs 13 cooling tubes and 14 fin rows in the front core plus 11 cooling tubes and 12 fin rows in the rear core, totaling 24 rows of tubes paired with 25 rows of 8mm tall multi-louvered fins. The 8368 ships with OEM-style inlet and outlet connections, pre-installed foam seals, and all hardware including the bracket for the OE expansion valve, requiring absolutely no modifications for installation. 100% aluminum construction with a satin black anti-corrosive powder coat finish and a 2-year limited warranty round out a unit that restores proper A\/C performance to these classic 911 platforms without compromise.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eParallel dual-core design far more efficient than the OEM serpentine tube

Questions\u003c\/h4\u003e\n\u003cstrong\u003eWhat Porsche models does the CSF 8368 fit?\u003c\/strong\u003e\n\u003cp\u003eThe 8368 fits 1989-1994 Porsche 911 (964) and 1995-1998 Porsche 911 (993) variants including Carrera 2, Carrera 4, Carrera 4S, Carrera S, RS America, Targa, Speedster, and Turbo models. See the full fitment table above for year-specific trim coverage.\u003c\/p\u003e\n\n\u003cstrong\u003eWhy does the 964\/993 A\/C system underperform after R134a conversion?\u003c\/strong\u003e\n\u003cp\u003eThe factory evaporator was designed around R12 refrigerant, which has a higher latent heat capacity than R134a. When the system is converted to R134a, the original serpentine-tube evaporator cannot transfer heat efficiently enough to compensate, resulting in poor cooling output. The CSF dual-core parallel-flow design in this evaporator specifically addresses this by doubling the effective cooling surface area and using modern microtube geometry that works with R134a system pressures and flow characteristics.\u003c\/p\u003e\n\n\u003cstrong\u003eDoes this evaporator require any cutting or modification to install?\u003c\/strong\u003e\n\u003cp\u003eNo. It is a true drop-in fit. The OEM-style inlet and outlet connections align with the factory A\/C lines, the included hardware reuses the OE expansion valve bracket, and the pre-installed foam seals mate directly to the factory evaporator housing. No cutting, drilling, or fabrication is required.\u003c\/p\u003e\n\n\u003cstrong\u003eDoes this evaporator work with an unconverted R12 system?\u003c\/strong\u003e\n\u003cp\u003eYes. It is compatible with both R134a and original R12 systems. The parallel-flow design performs well with either refrigerant, though the efficiency gains are most significant on R134a conversions where the factory evaporator typically underperforms.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat expansion valve is compatible with this evaporator?\u003c\/strong\u003e\n\u003cp\u003eThis unit includes the bracket for attaching the OE Porsche expansion valve. Compatible Porsche expansion valve part numbers are 92857312305 and 92857022300. Reuse of the existing OE expansion valve is supported; replacement is not required unless the existing valve is faulty.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat OEM part numbers does this evaporator replace?\u003c\/strong\u003e\n\u003cp\u003eThis unit replaces Porsche OEM part numbers 96457390100 (964-573-901-00) and 96457301300 (964-573-013-00). Cross-reference these against your specific chassis before ordering to confirm the correct application.\u003c\/p\u003e\n\n\u003cstrong\u003eHow does the 52mm core thickness compare to the factory unit?\u003c\/strong\u003e\n\u003cp\u003eThe factory OEM evaporator measures 67mm in core thickness. This dual-core unit is 52mm thick, which is 15mm slimmer. Despite being more compact overall, the parallel-flow dual-core architecture provides significantly more cooling tubes and fin rows than the factory serpentine design, resulting in better thermal performance in a smaller package.\u003c\/p\u003e\n\n\u003cstrong\u003eDoes replacing the A\/C evaporator require a full system recharge?\u003c\/strong\u003e\n\u003cp\u003eYes. Any time the A\/C evaporator is removed, the refrigerant must be recovered by a certified technician before disassembly and the system must be evacuated, leak-tested, and recharged with the correct refrigerant charge after installation. Professional A\/C service is required and is not a DIY procedure in most jurisdictions.\u003c\/p\u003e\n\n\u003cstrong\u003eDoes this evaporator address the white dust or debris issue found in 964\/993 A\/C systems?\u003c\/strong\u003e\n\u003cp\u003eYes. The white flakes commonly found in 964\/993 A\/C vents are caused by degradation of the foam coating on the original evaporator fins breaking down over time and entering the cabin airflow. This unit uses modern louvered aluminum fins with a durable powder coat finish, eliminating the foam-fin construction that degrades in the original unit.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat warranty does this evaporator carry?\u003c\/strong\u003e\n\u003cp\u003eThis unit is backed by CSF's 2-year limited warranty against defects in materials and workmanship from the date of purchase.
