• Description:

  This genuine Ford intake manifold gasket, part number YL3Z-9439-BA, is the factory driver-side (left-hand) intake manifold-to-cylinder-head gasket for Ford modular 4.6L and 5.4L two-valve V8 engines used in applications such as the Mustang GT, Crown Victoria, and other full-size cars and trucks of that era. The gasket seals the joint between the intake manifold and the cylinder head, maintaining an airtight boundary for the incoming air charge and preventing vacuum leaks that would upset the air-fuel mixture. It is manufactured to original Ford specifications with the correct port shapes, bolt-hole locations, and sealing beads for a precise fit on the driver-side head. Signs that this gasket needs attention include a rough or unstable idle, a lean running condition, hissing vacuum leaks, hesitation, or a check engine light for lean or misfire codes. The gasket is commonly replaced during intake manifold service or when addressing coolant or vacuum leaks at the manifold. Installing the correct genuine driver-side gasket restores a proper seal and smooth engine operation. This unit fits the left-hand head; confirm the engine and side against your vehicle before installation.
