Catalytic Converter for Ford Fusion (2013-2018) 1.5L 1.6L Rear Left & Right

Direct-Fit Rear Catalytic Converter Assembly for 2013-2018 Ford Fusion

What it Does: The catalytic converter assembly replaces degraded or clogged factory emissions units on the 2013-2018 Ford Fusion to restore factory exhaust velocity, clear diagnostic trouble codes, and ensure strict compliance with tailpipe emissions standards.

The Stock Ford Fusion Thermal Degradation & Catalyst Washcoat Erosion

Factory underbody catalytic converters on the CD4 platform are subject to aggressive exhaust gas temperatures produced by direct-injected, turbocharged engines. Over extended mileage, the stock washcoat on the internal ceramic honeycomb suffers from thermal degradation and carbon fouling due to blow-by and unburnt hydrocarbons. This leads to substrate fracturing, restricted exhaust gas scavenging, elevated backpressure that stresses the turbocharger turbine wheel, and persistent downstream oxygen sensor catalyst efficiency trouble codes such as P0420.

The Engineering Solution

Engineered as a bolt-on replacement, this rear catalytic converter assembly features a heavy-gauge Stainless Steel tubular casing built to withstand severe road vibration and thermal cycling. Internally, a high-flow flow-through ceramic honeycomb substrate is coated with an optimized precious-metal washcoat to maximize catalytic conversion without choking exhaust pulses. Precision laser-cut flanges, mandrel-bent routing, and factory-matched oxygen sensor bungs ensure a direct seal to factory mid-pipes using the included mounting hardware and gaskets without cutting, welding, or custom fabrication.

Frequently Asked Questions

Does this fit the CD4 Fusion?
Yes, this is a direct fit for the 2013-2018 Ford Fusion equipped with the 1.5L and 1.6L EcoBoost engine.

Will installing this converter clear my P0420 or P0430 DTC?
Yes, it provides the required chemical conversion efficiency to satisfy downstream O2 sensor parameters and extinguish catalyst-related check engine lights.

The Ford Commuter Reliability Standard

Engineered to withstand daily highway operating temperatures and winter road brines, this direct-fit unit preserves the CD4 chassis refinement by eliminating exhaust cabin resonance and maintaining smooth backpressure characteristics for reliable commuting performance.
