The MPI Automotive FX-422 is a set of extractors listed to fit the Mitsubishi Lancer CJ with the 2.0-litre or 2.4-litre 4B11/4B12 engine, from 2008 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, replaces the cast manifold bolted to the cylinder head with a set of tubes, giving each port its own runner before they merge. The aim is to reduce the back-pressure the engine works against as it clears spent gas. It's the first item in the exhaust, sitting right at the engine, with the rest of the system running behind it. On these four-cylinder Lancer engines 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 CJ Lancer fitment cover?

This set is listed for the Mitsubishi Lancer CJ running the 2.0-litre or 2.4-litre 4B11 and 4B12 engines, from 2008 onwards. Naming the engine codes pins the set to that generation rather than the earlier Lancers. Tube diameter, material and finish aren't published by the supplier in this listing, so we'd confirm those with MPI Automotive at order time rather than assume them for your car.

Will it suit my Lancer?

It's listed to fit the Mitsubishi Lancer CJ with the 2.0 or 2.4 4B11/4B12 engine from 2008. The engine code and the year of your car are what settle this set, so it's worth checking exactly which engine you have. Fitment is listed-to-fit rather than guaranteed, because feed data can be imperfect and the actual car is what confirms it. Send us your Lancer's details and we'll verify the FX-422 before you order.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits Lancer 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. Send us your Lancer's engine details and we'll check the FX-422 before booking the bay.
