Porsche AC Hose / Line / Pipe 99657310503 is a used genuine OEM part. This refrigerant hose, also known as an AC line, replaces superseded number 99657310502. Fits a range of naturally aspirated and turbocharged flat-six engines, including 2.5L, 2.7L, 3.2L, 3.4L, and 3.6L variants from Porsche 911 and Boxster applications. A failing AC hose often leads to refrigerant leaks, reduced cooling performance, or moisture entry that damages the compressor—prompt replacement prevents system contamination.
