Catalytic Converter for Ford F-150 (2015-2018) 3.5L Left & Right

Direct-Fit Left & Right Catalytic Converter Set for 2015-2018 Ford F-150 (P552)

What it Does: The Left & Right Catalytic Converter Set replaces worn or clogged factory converters on the 2015-2018 Ford F-150 to restore exhaust flow velocity, clear emissions trouble codes, and maintain factory backpressure levels.

The Stock Ford F-150 Catalyst Degradation

Under repeated towing loads and extended thermal cycling, the factory converter substrates on the P552 platform suffer internal thermal breakdown and carbon fouling. High exhaust gas temperatures from sustained twin-turbo boost degrade the original ceramic monolith, causing internal crumbling, exhaust choking, and persistent catalyst system efficiency trouble codes such as P0420 and P0430.

The Engineering Solution

Engineered as a direct bolt-on replacement, this converter pair features heavy-gauge Stainless Steel outer shells built to resist thermal expansion stress and corrosive road elements. High-efficiency Ceramic honeycomb substrates with targeted washcoats provide optimal catalytic reaction surface area to eliminate emissions faults without choking turbine discharge. Precision-aligned inlet and outlet flanges mirror OEM geometry to eliminate custom welding or pipe expansion during installation.
