The MPI Automotive EMG171 is an extractor/manifold gasket listed to fit the Holden 253 and 308 V8 engines. It's the flange seal between the cylinder head and the extractor or factory manifold, not the header itself.

What does this gasket cover?

The EMG171 is the exhaust-face gasket for the Holden 253 and 308 V8 — the red, blue and black-motor family. It seals each side of the vee where the extractor or factory manifold bolts to the head, so combustion gas stays in the runner rather than escaping at the flange. It's cut to the Holden V8 port pattern, which is why it's listed against those engines specifically.

What is an extractor gasket and what does it do?

An extractor gasket is the 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 keeps its shape through repeated heat cycles. On a V8 you seal two banks, so each side takes its own gasket. They're renewed whenever you fit extractors, change a manifold, or pull a head — a leaking one tends to tick or hiss under load. It's a routine sealing item rather than a performance part in its own right.

Will it suit my Holden V8?

The EMG171 is listed to fit the Holden 253 and 308 V8. Because it seals the engine's exhaust face, the key check is the engine itself and its flange pattern rather than the body it's fitted to. The supplier hasn't published a year range or model list here, so confirm your exact engine and flange with the workshop before ordering.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fits Holden V8 extractors and gaskets in-house across the Illawarra. The job means cleaning both faces, checking each flange is flat and not warped, and torquing the fasteners evenly so neither side of the vee is pinched. The EMG171 is supplied by MPI Automotive at an RRP of $15.25; contact us to confirm fitment and book the bay.

Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
