Walker 73042 Catalytic Converter - Left

Overview

Walker EPA 73042 is a direct-fit catalytic converter for select Ford F-150 applications. It is built for EPA-compliant use on OBDII vehicles and follows the fitment and emissions notes listed for each application.

Key Features

• Direct-fit catalytic converter for straightforward replacement.
• EPA-compliant design for approved federal-emissions applications.
• Steel body construction with a round housing profile.
• Single inlet and single outlet layout for the specified exhaust configuration.
• Walker Ultra Direct-Fit line for application-specific exhaust replacement.

Detailed Description

Walker 73042 is part of the EPA Ultra Direct-Fit catalytic converter line, which is built for import and domestic OBDII vehicles from 1996 and newer. This converter is engineered to match the listed Ford F-150 applications with a direct-fit layout and EPA-focused compliance. The steel body and round shape support a replacement that follows the original exhaust path more closely than a universal converter. This part cross-references Monroe Shocks & Struts (e.g., 21-465, FL3Z5E212C) for the same application.

Fits 2018-2020 Ford F-150, left. Fits 2015-2017 Ford F-150, left, with Federal Emission System; not legal for sale or use in California and other CARB-compliant states. Legal in New York and Maine on EPA Federal Emission Equipped Vehicles only.

What It Is Used For

• Replacing a worn or inefficient catalytic converter.
• Restoring exhaust aftertreatment performance on the listed applications.
• Addressing emissions-related fault codes tied to converter efficiency.
• Correcting exhaust flow issues caused by a damaged converter housing.

Installation Notes

Verify the emission system, position, and model year before installation. This part is listed for left-side Ford F-150 applications only, and the 2015-2017 fitment includes federal-emissions restrictions. Confirm all regulatory requirements for your state before use.

Quality Assurance

Walker Ultra Direct-Fit catalytic converters are built to comply with EPA standards and are intended for application-specific exhaust replacement on approved vehicles.
