MPI Automotive Jeep Grand Cherokee 4.0L 6 Cylinder 1996 - 2005 1J4G Extractor.
Category: Extractors and headers


The MPI Automotive FX-792 is an extractor set listed to fit the six-cylinder Jeep Grand Cherokee 4.0L, 1996–2005. It replaces the factory exhaust manifold at the cylinder head.
An extractor, or header, swaps the cast factory manifold for tuned-length tubes that merge downstream, aiming to reduce back-pressure off the head. On the inline-six 4.0L Grand Cherokee it's the front-most exhaust component, bolted straight to the engine. We can't publish power or sound figures for the FX-792 — the supplier doesn't, and we don't quote numbers we can't verify.
The FX-792 is listed to fit the 4.0L six-cylinder Grand Cherokee from 1996 to 2005. Confirm your exact engine and build with the workshop before ordering — the 4.0 inline-six is the key detail. We treat fitment as 'listed to fit' rather than guaranteed, because feed data can be imperfect.
Oak Flats Muffler Men fits Jeep extractors in-house. On the 4.0 six we check head-face condition, stud access and how the extractor mates to your existing downpipe before committing. Across a 1996–2005 span there were running changes to these Grand Cherokees, so confirming your exact build up front saves surprises in the bay. Send your Grand Cherokee's details and we'll confirm the FX-792 and book it in.
The FX-792 is an MPI Automotive part with a recommended retail of $1,176.73. As a Jeep header it may be ordered in rather than stocked, so ask us about availability when you book.
