Detailed Description

Apex AMS4932 is used to seal the upper fuel injection plenum during intake service on compatible Ford platforms, including Ford Mustang, Ford F-150, and Ford Econoline models. Proper plenum sealing helps maintain intake vacuum integrity and supports consistent engine operation after upper intake removal or service. This part number, AMS4932, is cataloged for 1997-2004 Ford applications with upper position fitment only.

What It Helps Address

• Upper intake vacuum leaks
• Air leakage at the plenum sealing surface
• Rough idle caused by intake sealing issues
• Loss of engine performance after intake service
• Reassembly needs after upper plenum removal

Installation Notes and Tips

Verify engine configuration and model year before installation. Clean the mating surfaces thoroughly and inspect the upper intake components for warpage, damage, or contamination before installing the new gasket set. Confirm the application is the upper position listed for your vehicle, since AMS4932 is not cataloged for lower intake use.
