• Description:

  This is the genuine Ford upper intake manifold gasket for the 00-04 Lincoln Navigator and Blackwood with the 5.4L DOHC InTech V8. It seals the joint between the upper intake manifold and the lower intake, maintaining the airtight boundary the engine relies on for correct fuel metering and idle quality. A failed or hardened intake gasket lets unmetered air leak into the intake tract, producing a rough or hunting idle, a lean condition, vacuum leak whistles, and stored fuel-trim or misfire codes, so a deteriorated gasket is a common driveability culprit on these engines. This genuine Ford gasket is made to the original specification for the DOHC InTech intake, which is distinct from the SOHC 5.4L gasket, so it matches the port and bolt pattern of this engine exactly and seals as designed. Installing the correct DOHC-specific gasket is important because the SOHC part will not seal this manifold properly. During service, clean both sealing surfaces thoroughly, inspect the manifold for warpage, set the gasket without sealant unless Ford specifies it, and torque the manifold fasteners in the correct sequence and value. Confirm the application against your specific 5.4L DOHC engine before ordering, since intake gaskets differ between the DOHC and SOHC versions.
