Detailed Product Overview

Mahle G31745 is a fuel injection throttle body mounting gasket made for vehicles that use a molded rubber throttle body-to-spacer seal. It is a direct-fit sealing component for service work on the throttle body assembly, helping restore the connection between the throttle body and spacer on Ford F-150, Ford Expedition, Lincoln Navigator, and related platforms. The G31745 part number is also a useful reference when cross-shopping throttle body gasket replacements for these applications.

This part cross-references FEL-PRO 61438 and Ford 3L3Z 9E936-AA for the same application.

What This Gasket Helps Address
