Fel-Pro 61438 is a rubber fuel injection throttle body mounting gasket for verified 5.4L V8 applications in the Ford F-150 and Mustang. It seals the throttle body mounting surface to help stop unmetered air from entering the intake, addressing rough idle, poor throttle response, vacuum-leak concerns, and check engine light issues tied to gasket failure.

Fel-Pro 61438 Features:

• Rubber construction provides the flexibility needed for a dependable seal at the throttle body mounting surface.
• Application-specific design is intended for fuel injection throttle body mounting locations rather than a universal cut-to-fit repair.
• Inside diameter measures 3.252 in. (82.6 mm), outside diameter measures 3.476 in. (88.2 mm), and thickness measures .250 in. (6.3 mm).
• Gasket is specified with 0 bolt holes, matching its intended mounting design for the listed application.
• Engineered for the real-world repair environment to help seal imperfect mating surfaces while meeting OE-style fit expectations.

Use this gasket when removing the throttle body for cleaning, replacing the throttle body, or diagnosing intake air leaks around the mounting flange. Clean the mating surfaces before installation and confirm vehicle fitment before ordering.
