Magnaflow 18-21 Ford Expedition Left Underbody 3.5L Direct Fit Catalytic Converter

If your Lincoln Navigator's check engine light is on and you suspect a catalytic converter issue, this Magnaflow Direct-Fit Catalytic Converter is a solid replacement. It's designed to meet Federal/EPA emissions requirements, helping you pass emissions tests and keep your Navigator running cleanly. This part is specifically made for the 2018-2023 Lincoln Navigator and the 2018-2022 Ford Expedition with the 3.5L engine.

Magnaflow builds this converter with free-flowing, mandrel-bent tubing and uses highly corrosion-resistant stainless steel for the construction, ensuring it holds up over time. They use 3D scanning during development to make sure the fit and function are just like the original equipment. The single laser fusion weld is designed to greatly reduce the chance of leaks, and its compact, low-mass design helps with thermal efficiency. Installation is straightforward because it's a direct-fit unit, meaning no cutting or welding is needed, and it includes essential gaskets and hardware to simplify the process.

This converter is built to meet or exceed Federal emissions requirements for OBDII Federally registered vehicles. Please note that this converter is not CARB approved and cannot be shipped to California.
