This Porsche 99610665103 coolant pipe / tube / line is a genuine OEM used part from a donor Boxster. Also supersedes 99610665102. Designed for the 2.5L, 2.7L, and 3.2L flat-six engines, this metal or plastic line routes coolant between engine and cooling system. Over time, these pipes can develop cracks or leaks at connection points, leading to coolant loss and overheating. A direct replacement restores proper flow and system pressure.
