Ford Falcon EA-AU 3.9 & 4.0L 6 Cylinder DSF Gasket (EMG156) fits selected vehicle applications.
Category: Extractors and headers


The MPI Automotive EMG156 is an extractor/manifold gasket listed to fit the Ford Falcon EA to AU with the 3.9 and 4.0-litre six-cylinder engine. It's the flange seal between the cylinder head and the extractor or factory manifold, not the header itself.
The EMG156 is the flat exhaust-face gasket for the Falcon straight-six across the EA to AU range, covering both the 3.9 and 4.0-litre versions. It seals the joint where the extractor or factory manifold bolts to the head, keeping the gas from each port inside the runner rather than leaking past the flange. It's cut to that inline-six port pattern, which is why it's listed against the EA–AU Falcon rather than as a generic Ford gasket.
An extractor gasket is the soft, replaceable seal between the cylinder head and the exhaust extractor or manifold. Exhaust gas leaves the head hot and under pressure, so the joint needs a gasket that holds its shape through repeated heat cycles. On a long inline-six the gasket has to seal a row of ports evenly. It's renewed whenever you fit extractors, swap a manifold, or pull the head — a failed one tends to tick or hiss under load. It's a routine sealing item rather than a performance part on its own.
The EMG156 is listed to fit the Ford Falcon EA to AU with the 3.9 and 4.0-litre six. That spans a long run of Falcons, so the gasket follows the engine and its exhaust face across those models. The supplier hasn't published exact build dates here, so confirm your engine and flange with the workshop before ordering.
Oak Flats Muffler Men fits Falcon six extractors and gaskets in-house across the Illawarra. The job means cleaning the full length of both mating faces, checking the flange is flat along the row of ports, and torquing the fasteners evenly so the seal isn't pinched at one end. The EMG156 is supplied by MPI Automotive at an RRP of $49.74; contact us to confirm fitment and book the bay.
