  Valve Cover Gasket, Gasket Intake Manifold

• Description:

  This is a Genuine Ford engine intake manifold gasket carrying Ford part number HL3Z-9439-C. The gasket fits 17-26 F-150 trucks equipped with the 3.5L EcoBoost twin-turbo V6. The part is supplied as a set containing three small oval gaskets serving both the left and right bank intake runners. This part number supersedes the earlier HL3Z-9439-A and HL3Z-9439-B references. The intake manifold gaskets are a critical sealing component on the turbocharged EcoBoost engines because any leak between the manifold and cylinder head will degrade boost pressure delivery to the cylinder and can trigger drivability concerns or check engine codes related to fuel trim or boost pressure. Genuine Ford gaskets use OEM specification material rated for the thermal cycling and boost pressures seen on the 3.5L EcoBoost. non-OEM gaskets at this location are a frequent source of post-service issues. This part ships in original Ford OEM packaging. Installation should follow the published Ford workshop procedure with attention to clean mating surfaces, correct gasket orientation in each runner port, and torquing of the intake manifold fasteners in the specified sequence to the factory torque value.

• Applications: 3.5L.
• Replaces:

  HL3Z9439A, HL3Z9439B
