FORD BA-BF-FG 4.0L 6 CYL HEADER FLANGE PLATE for selected vehicle applications.
Category: Extractors and headers


The MPI Automotive MHF4490 is a header flange plate listed to fit the Ford BA, BF and FG 4.0L six-cylinder. It is the flange that headers are built around for those engines.
This is a header flange plate — the machined plate that bolts to the cylinder head and that header tubes weld into. It is listed for the Ford BA, BF and FG 4.0L six-cylinder. It is a fabrication component, not a finished header or exhaust. RRP is listed at $128.66 AUD.
A header flange plate is the foundation an exhaust fabricator builds a header on: its bolt pattern and port shape must match the cylinder head exactly. Builders and workshops buy flange plates to fabricate or repair custom headers for a specific engine — here the long-running Ford 4.0L six used across the BA, BF and FG Falcon range. The supplier does not publish a tube size or material for this plate.
It is listed to fit the Ford BA, BF and FG 4.0L six-cylinder. Because flange dimensions must match your exact head, confirm your engine with the workshop before ordering — the wrong pattern will not seal.
Oak Flats Muffler Men works with flange plates like this as part of header fabrication and repair in-house across the Illawarra. We confirm the port pattern against your head before any cutting or welding. Send your engine details and we will advise on the right plate for the job.
