Detailed Description

Apex AMS11820 is an upper fuel injection plenum gasket set for vehicles that use a sealed intake plenum interface. This part cross-references common aftermarket application listings for the same fitment and is used on models such as the Ford Fusion, Ford Taurus, and Mazda CX-9. When the upper plenum seal is worn, damaged, or no longer sealing evenly, replacing it with the correct AMS11820 gasket set helps restore the intake sealing surface.

Common Uses

• Replacing a leaking upper intake plenum gasket
• Addressing vacuum leaks at the plenum-to-intake joint
• Correcting rough idle caused by intake sealing loss
• Restoring proper manifold sealing after intake service
• Servicing upper intake components on Ford, Lincoln, Mazda, and Mercury applications

Installation Notes and Tips

Confirm upper-position fitment before installation and match the vehicle by year, make, and model. Clean both mating surfaces thoroughly before assembly, and inspect the intake plenum and adjacent sealing surfaces for damage or warpage. Verify that the gasket aligns correctly during reassembly to avoid sealing issues. Use the part number AMS11820 when checking catalog fitment for the Ford Edge, Lincoln MKZ, or Mazda 6.

Quality Assurance
