The MPI Automotive EMG173 is an extractor/manifold gasket cut for the twin siamese port head, listed to fit the L200 and L300 (SF/SG/SH) 2.0-litre and 2.4-litre EFI Sirius engines (4G62/4G63/4G64) and the Hyundai G4CS. It's the head-to-extractor seal, not the header.

Why does the twin siamese port matter here?

The Sirius engine family ran more than one exhaust port pattern, and the EMG173 is cut specifically for the twin siamese port head — that's the detail that sets it apart from gaskets cut for equal-spaced ports on the same engine codes. Match the port layout and the gasket seals cleanly; mismatch it and you get a leak path no amount of torque will close. The Hyundai G4CS shares the relevant geometry, which is why it's listed alongside.

What does an extractor gasket do?

It's the replaceable seal between the cylinder head and the extractor or manifold, renewed whenever that joint is opened — new extractors, a head off, or a leak — because heat cycling hardens the old material so it won't reseal. It doesn't alter how the engine runs; its only job is to keep the joint gas-tight through repeated heat cycles. On these EFI Sirius fours that means holding a clean seal across the 2.0-litre and 2.4-litre variants the gasket is listed against.

Will it suit my engine?

The EMG173 is listed to fit the L200 and L300 SF/SG/SH on the 2.0-litre and 2.4-litre EFI Sirius engines (4G62/4G63/4G64) and the Hyundai G4CS, with twin siamese ports. Other port layouts within the same engine family take a different gasket, so confirm your head with the workshop before ordering.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fits these Sirius-engine manifolds and extractors in-house across the Illawarra. The job means cleaning both faces, confirming the siamese port layout matches the head in front of you, and tightening evenly so the gasket seals without distortion. The EMG173 is supplied by MPI Automotive at an RRP of $56.07; contact us to confirm fitment and book the bay.

Common questions

What does the EMG173 fit?
It's listed for the L200/L300 SF/SG/SH 2.0L/2.4L EFI Sirius 4G62/4G63/4G64 and the Hyundai G4CS, twin siamese ports. Confirm your head with the workshop first.
Why does the port layout matter?
The Sirius family came with more than one port pattern; this gasket is cut for the twin siamese port, so matching it avoids a mismatched seal.
Can you fit it?
Yes. Oak Flats Muffler Men fits these gaskets and extractors in the Illawarra; contact us to book.
