Catalytic Converter for Ford Explorer (2016-2019) 3.5L Front Left & Right

Direct-Fit Front Manifold Catalytic Converters for 2016-2019 Ford Explorer (U502)

What it Does: The front manifold catalytic converter pair replaces degraded factory manifold converters on the 2016-2019 Explorer to clear P0420/P0430 DTC faults, prevent exhaust leaks, and restore proper exhaust flow velocity.

The Stock Ford Explorer Converter Degradation

Factory manifold catalytic converters on the U502 chassis frequently experience premature thermal degradation, core fracturing, and washcoat poisoning over high-mileage heat cycles. On the transversely positioned Duratec 35 3.5L V6 engine, compact engine bay packaging creates extreme radiant heat pockets. This sustained thermal stress leads to exhaust flange warpage, internal ceramic brick crumbling, elevated backpressure, and recurring catalyst efficiency diagnostic trouble codes.

The Engineering Solution

This direct-fit Bank 1 and Bank 2 manifold assembly is constructed from corrosion-resistant aluminized steel with heavy-gauge flanges to eliminate warping under cyclic expansion. High-efficiency ceramic monolith substrates provide maximized surface area for catalytic reduction and oxidation reactions, accurately matching factory oxygen storage capacity (OSC) to prevent check engine lights. Mandrel-formed collector sections maintain cylinder-to-cylinder scavenging balance while withstanding severe operating temperatures without cracking.
