This Exhaust Systems Australia manifold cat-converter is listed to fit the Kia Optima 2.4L petrol JF (11/15-01/20) and the Hyundai Sonata 2.4L petrol LF (10/14-01/20), to Euro6. It is a combined exhaust manifold and catalytic converter for the front of the system.
What is a manifold cat-converter?
This part combines the exhaust manifold that collects gas from the cylinders with the catalytic converter that treats it, in a single casting. On these 2.4L Hyundai and Kia cars the close-coupled cat warms up quickly, so manifold and converter are made as one bolt-on unit. Replacing it restores both the gas path and the emissions hardware in the one part, with the Euro6 reference noting the emissions standard it is built to.
Why does it cover Optima and Sonata?
Hyundai and Kia shared the 2.4L petrol engine across the Optima JF and the Sonata LF, so one manifold-cat pattern can span both badges. The listing scopes the Optima to 11/15-01/20 and the Sonata to 10/14-01/20. Shared engines do not guarantee an identical part across every variant, so the application list and date ranges are the guide rather than the badge.
Will it suit my Optima or Sonata?
It is listed for the 2.4L petrol Optima JF and Sonata LF in the build windows above. Because body codes and dates matter on these cars, confirm your exact model, engine and build date with the workshop before ordering rather than going by the badge alone.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men fits manifold cat-converters in-house across the Illawarra. We confirm the unit against your car, seat the flange gaskets and reconnect the oxygen sensors so the engine reads correctly. Supplied by Exhaust Systems Australia at $550 AUD; send your model, engine and build date and we will confirm the right part before booking the bay.
