Some 2021-2022 F-150 Raptor/Tremor vehicles equipped with a 3.5L EcoBoost engine may experience reduced engine power with an illuminated malfunction indicator lamp (MIL) and diagnostic trouble code (DTC) P0299 stored in the powertrain control module (PCM). This may be due to the upper radiator air deflector fit and possible interference with the engine air cleaner fresh air inlet. To correct the condition, follow the Service Procedure to replace the affected turbocharger and related components.
