What this expansion valve does:
• Regulates refrigerant flow between the condenser and evaporator
• Maintains optimal pressure for steady and efficient cabin cooling
• Prevents evaporator freeze-up and helps protect the A/C compressor

Location: Installed in the A/C system, positioned between the condenser and the evaporator.

Over time, expansion valves can clog, stick, or wear out, leading to poor cooling, fluctuating cabin temperatures, or compressor strain. Replacing with a genuine Porsche 92857312305 valve restores factory-level cooling efficiency, system reliability, and passenger comfort.
