  Radiator Support Air Duct, Duct Air

• Description:

  This is a genuine Ford passenger-side radiator support air duct for the 18-20 F-150. It is the right-side counterpart to the driver-side duct and shares the same general construction, with mirrored geometry suited to the passenger-side airflow path between the front bumper opening and the radiator and cooling fan area. The duct provides controlled airflow management on the passenger side of the cooling system, maintaining cooling capacity at idle and low-speed driving and contributing to the overall aerodynamic behavior of the front end. Failure modes include cracked plastic from impact damage, heat-induced warping in extreme conditions, broken mounting tabs, and damaged sealing interfaces at the joints with adjacent components. Symptoms include elevated coolant temperatures during heavy load or air conditioning operation, particularly in stop-and-go driving conditions, and reduced highway fuel economy from disrupted aerodynamic behavior. The genuine duct carries the correct mounting geometry, sealing interface, and airflow management features for the F-150 application. Substituting a non-OEM duct can produce fit problems with the radiator support and adjacent components and may compromise cooling system efficiency. Replacement requires partial disassembly of the front bumper area for access, careful release of retention clips, removal of the old duct, and methodical reinstallation with attention to all sealing surfaces and mounting tabs. The ducts on both sides should be inspected together since impact or heat damage often affects both pieces. This listing covers the individual duct only.
