Fuel Injection Plenum Gasket Set for Lincoln LS

The Apex AMS4992 fuel injection plenum gasket set is built for upper intake sealing on select Lincoln LS applications. It is a direct-fit sealing component for 2002-2005 Lincoln LS, Upper, helping restore the intake plenum seal where vacuum leaks and air intrusion can affect engine performance.

Key Features

  • Fuel injection plenum gasket set for upper intake sealing
  • Fits 2002-2005 Lincoln LS, Upper
  • Supports proper sealing between intake components
  • Designed for air and fuel delivery service work
  • Part number AMS4992 for easy identification

Detailed Description

Apex AMS4992 is a replacement gasket set for the upper fuel injection plenum on 2002-2005 Lincoln LS models. This sealing component is used in the intake system to maintain a secure connection between mating surfaces and help preserve consistent airflow and engine operation. If you are servicing a Lincoln LS intake leak, replacing a worn plenum gasket with the correct AMS4992 application can restore the original seal at the upper intake location.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Repair Uses

  • Intake manifold or plenum vacuum leak diagnosis
  • Rough idle caused by degraded upper intake sealing
  • Air leakage at the fuel injection plenum interface
  • Maintenance on 2002-2005 Lincoln LS upper intake service
  • Replacement of a damaged or compressed gasket seal

Installation Notes

Verify the vehicle year, make, model, and upper position before installation. Clean both mating surfaces thoroughly and inspect the intake components for warpage, cracks, or contamination before fitting the new gasket. Follow the factory service procedure and torque sequence for the Lincoln LS intake assembly to help achieve an even seal.
