• Description:

  This is a genuine Ford intake manifold gasket for 5.4L engines used across F-150, E-Series, Expedition, Excursion, and Super Duty applications. The gasket seals the intake manifold to the cylinder head so intake air is delivered to the cylinders without leaking and without drawing unmetered air. A sound intake seal maintains correct airflow and a stable air-fuel mixture, preventing the vacuum leaks that cause rough idle and driveability faults. Owners replace this gasket during intake manifold removal, when servicing the engine top end, or when chasing a vacuum leak, rough idle, lean codes, or a hissing intake leak on the 5.4L. A failed or distorted intake gasket lets unmetered air enter and can upset idle quality and trigger trouble codes. Built to Ford specifications, the gasket provides the correct port shape, bolt pattern, and sealing material to seat between the manifold and head without modification. It fits the 5.4L engine across these applications, positioned on the appropriate bank. Because the gasket is shared across several lines, confirm your engine and side before ordering. Clean the sealing surfaces of old gasket material, inspect the manifold for warpage, and torque the manifold fasteners in the proper sequence to ensure an even, leak-free seal.
