The 99657310803 AC hose from Porsche serves as the refrigerant line for the H6 engine range in the 911 and Boxster. This used OEM pipe carries coolant between components; a failing line often causes a gradual refrigerant loss, reducing air-conditioning cooling performance. It is sometimes called an AC line or pipe.
