FORD 4.0L 6 CYL ALLOY HEAD 1 3/4in for selected vehicle applications.
Category: Extractors and headers


The MPI Automotive MHF4470A is a 1-3/4in header flange listed to fit the Ford 4.0L six-cylinder alloy head. It is the flange that headers are built around for that engine.
This is a header flange — the machined plate that bolts to the cylinder head and that header tubes weld into. It is listed for the Ford 4.0L six-cylinder alloy head with 1-3/4in tube openings. It is a fabrication component, not a finished header or exhaust. RRP is listed at $135.09 AUD.
A header flange is the foundation a fabricator builds a header on. The bolt pattern and port shape must match the cylinder head exactly — and the alloy-head Ford 4.0L six uses its own pattern, so a flange cut for the alloy head is specific to it. The tube openings here are 1-3/4in, setting the primary tube size. The supplier does not publish a material for this flange.
It is listed to fit the Ford 4.0L six-cylinder alloy head. Because head patterns differ, confirm you have the alloy head with the workshop before ordering — the wrong flange will not seal.
Oak Flats Muffler Men works with flanges like this as part of header fabrication and repair in-house across the Illawarra. We confirm the head type and tube size before cutting or welding. Send your engine details and we will advise on the right flange.
