▶ Vehicle Fitments
The MagnaFlow California Grade CARB-compliant direct-fit catalytic converter, part 4583087, is designed to replace the original converter and help keep the check engine light off. Its free-flowing mandrel-bent tubing supports exhaust flow, while corrosion-resistant stainless steel construction is built for durability. The spun-body design replicates the original equipment configuration, and a single laser fusion weld helps reduce the possibility of leaks. A compact, low-mass construction promotes thermal efficiency. MagnaFlow uses 3D scanning during development to help ensure the converter fits and functions like the original equipment. The replacement is designed to meet or exceed California Air Resources Board requirements and has undergone additional testing for CARB compliance.
This converter is designed for 2003–2004 Ford Expedition models equipped with the 5.4L engine. It interchanges with OE part numbers 2L1Z-5E212-CA and 4L1Z-5E212-BA, among others. The direct-fit design is intended for the listed vehicle application and can be installed with proper tools without cutting or welding. It is a replacement catalytic converter for road use where applicable, including California and other CARB-restricted states, subject to the stated vehicle fitment and emissions requirements. Confirm the vehicle’s year, model, engine, and original part compatibility before installation. No additional kit contents are specified.
