URO 64218367790 HVAC Heater Hose

BMW Heater Hose Replacement

This URO HVAC heater hose is a direct-fit replacement for select BMW E30 and E34 applications that use the inlet at the additional thermostat with an L-shaped routing. Built to match the OE hose shape, it supports clean installation and proper underhood appearance on BMW 325i, 325is, 325iX, 325e, and 325es models.

Part number 64218367790 is made with EPDM material that resists engine heat, ozone, and electrochemical degradation. If you are replacing a worn BMW heater hose on a 1984-1995 325-series vehicle, this hose follows the original routing for a factory-style service fit.
