The MPI Automotive MHF4002 is a header flange listed to fit the Ford 5.4L Boss V8. It is the machined plate that headers are built around for that engine, not a finished header.
What does the MHF4002 cover?
This is a header flange — the plate that bolts to the cylinder head and that header tubes weld into. It is listed for the Ford 5.4L Boss V8. It is a fabrication component rather than a complete header or exhaust, and its RRP is listed at $71.08 AUD. The supplier does not publish a tube size for this flange.
What is a header flange and who uses one?
A header flange is the foundation a fabricator builds a header on: the bolt pattern has to match the cylinder head, and the flange sets where the primary tubes begin. The 5.4L Boss is the quad-cam V8 used in Ford's performance Falcons, so a flange cut to its port pattern lets a builder fabricate or repair headers that bolt straight to that head. Builders and workshops buy flanges like this rather than a finished header when they are making something custom. Without a published tube size, the primary diameter is confirmed against the build at the workshop.
Will it suit my Ford 5.4L Boss?
It is listed to fit the Ford 5.4L Boss V8. Because the flange pattern must match your exact head, confirm your engine with the workshop before ordering — the wrong pattern will not seal.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men works with flanges like this as part of header fabrication and repair in-house across the Illawarra. We confirm the Boss port pattern against your head before any cutting or welding, and we set the primary size to suit the build. Send your engine details and we will advise on the right flange.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
