• Description:

  This is a Genuine Ford fuel injector identified as the upper port injector carrying Ford part number HL3Z-9F593-A. The injector fits 17-22 F-150 trucks equipped with the 3.5L EcoBoost twin-turbo V6, along with related Expedition and Lincoln Navigator applications using the same engine, with the early 22 service window end and a starting build date of 09/26/16. The injector is supplied with O-rings as called out in the parts catalog. The 3.5L EcoBoost uses a dual injection system with both port fuel injectors and direct injectors, and this part is the port injector serving the intake runner side of the dual injection arrangement. Correct port injector flow rate is critical to fuel trim balance and to drivability behavior at light load conditions where port injection is the dominant fueling strategy. Genuine Ford injectors are flow matched and electrically matched to the engine calibration. This part ships in original Ford OEM packaging with the required O-rings. Installation should follow the published Ford workshop procedure including light lubrication of the O-rings with clean fuel, careful seating in the rail and intake runner, torquing of any associated retaining hardware, and verification of no fuel leakage at the rail under operating pressure.
