  Gasket, Intake Manifold Upper Seal

• Description:

  This genuine Ford gasket seals the throttle body to the intake manifold on the 4.6L and 5.4L three-valve modular V8. It maintains an airtight joint at the throttle body flange, which is essential for accurate idle control, stable air-fuel metering, and smooth throttle response. A failed or hardened gasket here can cause unmetered air to enter the intake, leading to a rough idle, lean codes, or hesitation. Applications include the new-style F-150 built from 2004 to 2008, Lincoln Navigator and Mark LT, Ford Explorer and Mercury Mountaineer, and F-250 and F-350 Super Duty fitted with the three-valve V8. As original equipment it matches the factory bore and bolt pattern, so it locates correctly and seals without additional sealant. Always replace this gasket any time the throttle body is removed for cleaning or service, clean both mating faces first, and tighten the throttle body fasteners evenly to the specified torque to ensure a reliable seal.

• Applications: F150 NEW STYLE 2004-08, MARK LT.
