• Description:

  This is an exhaust front pipe nut, base part HN1, used at the front pipe, manifold, or converter flange across a broad range of Ford vehicles including E-Series, F-150, Explorer, and Mustang with engines from 2.0L through 6.2L. The dominant catalog name is front pipe nut, appearing also as exhaust nut and manifold nut on related diagrams. Sample applications are listed here as examples rather than a finite list. The nut clamps a hot exhaust flange so the joint seals and does not leak combustion gases, and because exhaust hardware runs through repeated heat cycles it tends to seize or back off. A loose or missing nut produces an exhaust tick or leak, a possible check-engine light from upstream oxygen-sensor readings, and increased noise. It is good practice to replace exhaust hardware rather than reuse corroded fasteners. Ford does not publish a single finite vehicle list for this universal fastener, so confirm fit for your specific vehicle by VIN before ordering. This is a multi-year service part that fits across the model years of the listed Ford applications.
