A used OEM Porsche coolant hose (supply), part number 99610621209, also superseding 99610621204 and 99610621203. This genuine water hose delivers coolant from the system to the engine on Boxster and Cayman models with the 2.7L, 3.2L, or 3.4L flat-six (H6) engines. Over time, factory coolant hoses can crack or develop pinhole leaks, leading to gradual coolant loss, visible drips, and risk of engine overheating. Replacing with a genuine used hose restores the original routing and fit without aftermarket guesswork.
