Used BMW heater coolant hose / line (inlet), OEM part number 9307241 — a genuine factory hose removed from a donor vehicle. Also known simply as the heater inlet hose, this line supplies hot coolant from the engine to the heater core. A cracked or clogged hose can cause insufficient cabin heat or coolant loss. This specific hose fits BMW’s S55 3.0L twin-turbo I6 (2979cc DOHC) found in M2, M3, and M4 models.
