Seal the throttle body to the intake and keep incoming air properly metered with the MAHLE Fuel Injection Throttle Body Mounting Gasket, part number G31586. It installs as a direct-fit replacement across a wide range of Ford vans and trucks, including the 2003-2014 Ford E-150, 2003-2014 Ford E-250, 2000-2016 Ford E-350 Super Duty, 2000-2005 Ford Excursion, 2000-2004 Ford Expedition, and 2000-2003 Ford F-150 — see the Buyer's Guide tab for the full list.
- Seals the throttle-body joint: forms the seal between the throttle body and the intake manifold so air stays metered as it passes the throttle.
- Guards against vacuum leaks: a cracked or hardened gasket can let unmetered air past the throttle — if that gasket leak is the cause of a lean condition or rough idle, this replaces it.
- Direct-fit replacement: serves as a direct-fit replacement for the original throttle body mounting gasket on the listed applications.

Frequently Asked Questions
What does this gasket do?
