"Reference OE Number: 17127537107 17127593490colour: black- EFFICIENT VENTILATION: The engine crankcase ventilation hose ensures proper ventilation of the engine crankcase, thereby releasing excess pressure and reducing the risk of engine damage.- Function: When the engine is running at high speed, more soot enters the intake system than at low speed, causing the engine to backfire. It can cut off ventilation and prevent crankcase leakage.- Keep the engine clean: The crankcase ventilation device not only discharges foreign gases and foreign substances, but also filters out particulate matter entering the crankcase.ve yo"
