MagnaFlow Conv DF 04 Ford Freestar 3.9L

If you're working on a 2004-2007 Ford Freestar or a 2004-2007 Mercury Monterey and need to replace the catalytic converter, this direct-fit unit from Magnaflow is a solid option. It's designed to keep your check engine light off and ensure your vehicle meets federal emissions standards. Magnaflow uses advanced 3D scanning during their research and development process to make sure this converter matches the original equipment in both fit and function, so you won't have to worry about it not lining up correctly.

This converter is built with free-flowing, mandrel-bent tubing, which helps maintain exhaust flow without restrictions, supporting factory performance and fuel efficiency. The construction uses high-strength 410 and 308 stainless steel for the tubing, hangers, and welds, offering excellent resistance to corrosion and a long service life. The single laser fusion weld is designed to minimize the chance of exhaust leaks, and its compact, low-mass design contributes to better thermal efficiency. Because it's a direct-fit design, installation is straightforward with the proper tools, meaning no cutting or welding is required, making it a job you can often do yourself.

This Magnaflow catalytic converter is EPA-compliant for OBDII federally registered vehicles, meaning it meets federal emissions requirements. It's important to note that this converter is not CARB approved and cannot be shipped to California. It interchanges with OE part numbers like 3F2Z-5F250-AA and 3F2Z-5F250-EB.
