The MPI Automotive MHF4001 is a 1⅞in header flange cut for the Ford 5.0L Coyote V8 — the machined plate that locates a header's primary tubes to the cylinder head, sold as a standalone fabrication component for building or repairing extractors.

What does a header flange do?

The flange is the thick, machined plate that bolts to the cylinder head and that each primary tube of a header welds into. It fixes three things at once: the port pattern that lines up with the head, the bolt locations that clamp it down, and the tube bore the primaries weld into — drilled here for 1⅞in. On its own it's a starting point for fabrication, not a finished exhaust part you bolt to a car; the rest of the header gets built up from it.

Why 1⅞in for the Coyote?

This flange is cut to the Ford 5.0L Coyote port pattern and to a 1⅞in tube bore. The larger 1⅞in primary suits a high-revving, free-breathing modern V8 like the Coyote, which is why a header built on this flange is sized that way rather than to a smaller tube. The flange simply sets that bore at the head end, so whatever tubes are welded in carry the 1⅞in size through from the port.

Will it suit my Coyote build?

It's listed for the Ford 5.0L Coyote V8 with 1⅞in tube and no further detail published, so it's matched on the Coyote port pattern and tube size rather than a vehicle bolt-up. We confirm your head matches the listing before the flange goes into a build, and check it against the tube you intend to run. As a component part it's often a special-order item; RRP is listed at 71.08 AUD, and Oak Flats Muffler Men can source and fabricate around it across the Illawarra.

Common questions

What tube bore is the MHF4001 drilled for?
1⅞in — the bore the Coyote header tubes weld into at the flange.
Is this a complete header or just the flange?
Just the flange — a fabrication component for building or repairing a Coyote header. Oak Flats Muffler Men in the Illawarra can guide the rest of the job.
