Heater hose (supply side) for the BMW N52/N54 3.0L engine cooling/heating circuit, carrying hot coolant from the engine to the heater core. Made from reinforced rubber to the factory diameter, bend radius and length; common failure points are splitting at the hose clamp, swelling, cracking or breaking with age, which can cause coolant loss and loss of cabin heat.
