The MPI Automotive FX-572 is an extractor set listed to fit the Nissan Navara D21 4WD 2.4L with the round-port KA24E head. It replaces the factory cast manifold on that four-cylinder D21 with a tube-style header.

What does this extractor set cover?

This is a header replacement for the front of the exhaust on the four-cylinder 4WD D21 Navara. As an in-line four, it covers a single bank, swapping the cast factory manifold for tubular runners that merge into one collector. The listing specifies the 2.4L round-port head and the 4WD D21, which matters because Nissan ran more than one port shape on this engine family — the FX-572 is matched to the round-port version, so the head pattern is the key thing to check.

What's an extractor and what does it change?

An extractor bolts to the cylinder head in place of the factory manifold. The cast item routes exhaust gas through short, uneven passages; an extractor uses tubes of more even length to merge that gas more smoothly, aiming to ease back-pressure out of the head. It's the front-most and hottest part of the system. On this 2.4L four, the port shape determines whether the flange will line up, which is why round-port and other heads get separate part numbers.

Will it suit my D21 Navara?

The FX-572 is listed to fit the round-port 2.4L 4WD D21 Navara. Because the same engine family came with different ports, confirm your head pattern and drivetrain with the workshop before ordering — a square-port or 2WD example may need a different set.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fits Navara extractors in-house across the Illawarra. A four-cylinder header swap means removing the old manifold, fitting fresh gaskets and reconnecting the front pipework, with a check that the flange matches the head. The FX-572 is supplied by MPI Automotive at an RRP of $545.37; contact us to confirm availability and book the bay.
