The MPI Automotive EMG171-B20 is a pack of 20 extractor gaskets listed to fit the Holden 253 and 308 V8. It is the bulk-20 pack of the sealing gasket for those engines.

What is in the EMG171-B20?

This is a pack of 20 of MPI's extractor gasket for the Holden 253 and 308 V8. Each gasket seals the flange between the extractors or manifold and the cylinder head, so exhaust gas does not leak at the joint. They are consumable sealing parts rather than performance parts; the bulk-20 pack suits a workshop or builder who fits these Holden V8s often and wants a larger run of gaskets under one part number.

What is an extractor gasket and why does it matter?

An extractor gasket sits between the head's exhaust ports and the extractor or manifold flange, sealing each joint so spent gas leaves through the system rather than escaping at the face. It is a wear item: the heat-cycling and the act of unbolting the extractors tends to crush and distort the gasket, so a fresh one goes on every time the headers come off. The EMG171-B20 is purely the quantity option of that same Holden 253/308 gasket.

Why buy a pack of 20?

Anyone working on Holden 253 and 308 V8s regularly goes through these gaskets, since they are replaced each time the extractors are removed. The EMG171-B20 keeps twenty on hand in one part number, which is more convenient than ordering singles. The individual gasket fits the same engines; this pack only changes the quantity, not the fitment.

Will it suit my Holden V8, and what does fitting involve at our Illawarra workshop?

The EMG171-B20 gaskets are listed to fit the Holden 253 and 308 V8. Confirm your engine is the 253 or 308 with the workshop before ordering, since the gasket has to match that head's port and bolt pattern. Oak Flats Muffler Men supplies and fits these gaskets in-house across the Illawarra: we fit a fresh gasket whenever a Holden V8's extractors come off, clean the faces and torque the flange evenly. Supplied by MPI Automotive at $222.11 AUD for the pack of 20.

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