Magnaflow 03-04 Ford Expedition 5.4L Direct Fit Converter

Magnaflow is well-known for its exhaust components, and this direct-fit catalytic converter is built to keep your 2003-2004 Ford Expedition running smoothly. If your check engine light is on and you suspect a catalytic converter issue, this part is designed to replace the original and help restore proper emissions control. It’s specifically made for the 5.4L engine in your Expedition, ensuring it functions like the factory part.

This converter is constructed from strong 16-gauge 409 stainless steel tubing, which offers excellent resistance to corrosion and a long service life. Magnaflow uses advanced 3D scanning during their research and development to make sure this converter fits precisely and performs as expected, replicating the original equipment's flow dynamics. The spun body design features a single laser fusion weld, which significantly reduces the chance of leaks. Its compact, low-mass design also helps with thermal efficiency. Because it's a direct-fit unit, installation is straightforward, with no cutting or welding needed, and it comes with the necessary gaskets and hardware to simplify the job.

This Magnaflow converter is designed to meet or exceed California Air Resource Board (CARB) requirements. It has undergone additional testing to comply with CARB guidelines, making it legal for use in California and other states with strict emissions standards. This part interchanges with OE parts 4L1Z-5E212-BB and 3L1Z-5E212-CB.
