Mopar 52022389AB Genuine OEM Make Up Air Hose PCV Crankcase Vent Hose

The Mopar 52022389AB Make Up Air Hose is a genuine OEM replacement crankcase ventilation hose designed to restore proper airflow in the positive crankcase ventilation (PCV) system. Also known as an air intake coupling or PCV valve hose, this make-up air hose ensures fresh air is drawn into the crankcase to replace blow-by gases being evacuated, keeping the engine's ventilation system functioning as designed.

As a direct-fit OEM component, this hose is manufactured to the exact specifications of the original part — ensuring proper sealing, routing, and connection to the intake system. It is compatible with the 2.4L I4 MultiAir and 2.4L I4 Zero Evap M-Air engines, including both standard and engine stop-start (ESS) variants, paired with the 9-speed 948TE FWD automatic transmission.
