Detailed Description

This catalytic converter is a fitment-specific exhaust replacement for Ford Explorer, Ford Explorer Sport Trac, and Mercury Mountaineer applications listed in the fitment table. Davico 19003 uses OE sample parts as the basis for its shape and function, and the catalyst is selected to meet the demands of OBDII-equipped vehicles. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Failed catalytic converter efficiency codes.
• Restricted exhaust flow from a worn converter.
• Emissions test failures tied to converter performance.
• Fitment issues caused by non-OE-style exhaust geometry.
