Holden Commodore VN VP VQ VR VS VT 5.0L EFI Square Port Extractor Gasket (SKU: EMG170) Engineered for a wide range.
Category: Extractors and headers


The MPI Automotive EMG170 is an extractor gasket listed to fit the Holden Commodore 5.0L EFI with the square-port head. It's the sealing piece between the head and the extractors, not the extractors themselves, so it's the consumable you replace whenever those joints come apart.
An extractor gasket seals the joint between the cylinder head's exhaust ports and the extractor flange. It's a wear item: every time the extractors are unbolted, or when a leak develops, you fit a fresh gasket so the joint stays gas-tight. The EMG170 is cut for the square-port pattern on the 5.0L EFI Commodore head, which matters because Holden ran more than one port shape across these engines and the wrong pattern won't seal. There are no performance figures attached to a gasket — its job is simply to keep the seal honest so the extractors flow as intended.
It's listed to fit the Holden Commodore VN, VP, VQ, VR, VS and VT with the 5.0L EFI square-port engine. The square-port qualifier is the one to check — confirm your head's port shape and build with the workshop before ordering, because feed data covers the listing, not your specific car.
A gasket is a sealing component, not an emissions part, so it doesn't change the registration status of your vehicle on its own. What matters for compliance is the rest of the exhaust it's bolted into. If you're unsure how your full system sits, raise it with the workshop when you book.
Oak Flats Muffler Men fits and replaces extractor gaskets like the EMG170 as part of extractor work across the Illawarra. We confirm the port pattern, clean the mating faces, and torque the flange evenly so the new gasket seats properly. Bring the car in and we'll check the square-port fitment before we start.
