The MPI Automotive EMG058 is an extractor/manifold gasket listed to fit the Jeep CJ series, Wrangler YJ, and 1981-1986 SJ and J-series with the 4.2-litre (232ci/258ci) six-cylinder engine. It's the head-to-extractor seal, not the header itself.
What does this gasket cover?
The EMG058 is the flat exhaust gasket for the 4.2-litre AMC six — listed in 232ci and 258ci form — across the Jeep CJ series, Wrangler YJ and the 1981-1986 SJ and J-series. It seals the joint where the extractor or factory manifold meets the cylinder head, keeping exhaust gas in the runner rather than leaking at the flange. It is matched to that in-line six's port pattern, which spanned several Jeep bodies.
What is an extractor gasket and what does it do?
An extractor gasket is the replaceable seal between the cylinder head and the extractor or manifold. It is 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. On an in-line six the head runs a single exhaust face. A worn gasket ticks or hisses under load and can let fumes past. On a hard-used 4x4 six like the Jeep 4.2 it is a routine renewal; its job is to keep the joint sealed through the engine's heat cycles.
Will it suit my Jeep?
The EMG058 is listed to fit the CJ series, Wrangler YJ and 1981-1986 SJ and J-series with the 4.2-litre (232ci/258ci) six. Other Jeep engines take different gaskets, so confirm your engine and body with the workshop before ordering.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men fits Jeep manifolds and extractors in-house across the Illawarra. The job means cleaning both faces, checking the single flange is flat, and tightening evenly so the gasket seals without distortion. The EMG058 is supplied by MPI Automotive at an RRP of $59.76; contact us to confirm fitment and book the bay.
