The MPI Automotive FX-421 is a set of extractors listed to fit the Hyundai Sonata with the 2.4-litre 4G64 engine, from 1989 onwards. It replaces the factory cast exhaust manifold at the cylinder head with a tubular extractor design.

What's an extractor and what does it do?

An extractor, or header, swaps the cast manifold bolted to the cylinder head for a set of tubes, giving each port its own runner before they merge. The aim is to cut the back-pressure the engine works against as it pushes spent gas out. It's the first item in the exhaust line, sitting right at the engine, with the rest of the system running behind it. On the four-cylinder 4G64 that's a single tubular set. It's a breathing change at the head only; it doesn't alter the engine's capacity or its fuelling.

What does the Sonata fitment cover?

This set is listed for the Hyundai Sonata running the 2.4-litre 4G64 four-cylinder, from 1989 onwards. Naming the engine code keeps the set tied to that engine rather than the other units the Sonata was offered with. Tube diameter, material and finish aren't published by the supplier here, so we'd confirm those with MPI Automotive at order time rather than assume them.

Will it suit my Sonata?

It's listed to fit the Hyundai Sonata with the 2.4 4G64 from 1989. The engine code and year of your car are what settle this set, so it's worth confirming exactly what's under the bonnet on an older car like this. Fitment is listed-to-fit rather than guaranteed, because feed data can be imperfect and the actual vehicle is what confirms it. Send us your Sonata's details and we'll check the FX-421 before you order.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits Sonata extractor sets in-house across the Illawarra. The job means unbolting the old manifold from the head, sealing the new tubular set with fresh gaskets, and confirming it ties cleanly into the existing pipework behind it. On a car of this age we'll also check the surrounding fasteners before committing. Send us your Sonata's engine details and we'll verify the FX-421 before booking the bay.
