URO Coolant Return Hose for Porsche 986 Boxster Tiptronic (1997–2004)

This molded URO hose connects the coolant return pipe at the engine-side four-way hose circuit on the matching 986 Boxster Tiptronic installation. It replaces a short return connection, rather than the complete multi-branch hose assembly. Match the pipe ends and transmission configuration before ordering.

Fitment & Compatibility

The 1997–2004 Boxster years below must be read with the Tiptronic-only restriction. The original Porsche diagram distinguishes production versions, and the replacement-reference family spans those versions. Compare the actual return hose and reference on early cars; do not apply it to a manual-transmission car based on model year alone.

With over 20 years of Porsche parts experience, PMB Performance can help identify coolant hoses by VIN and a photo of the installed pipework.
