Catalytic Converter for Ford Fiesta (2011-2019) 1.6L

Direct-Fit Emissions Catalytic Converter for 2011-2019 Ford Fiesta

What it Does: Replaces a degraded or clogged factory catalytic converter assembly to restore proper exhaust velocity, engine efficiency, and tailpipe emissions compliance on 1.6L Fiesta models.

The Stock Fiesta Exhaust Restriction

Over extended heat cycles, the factory converter on the 1.6L Duratec suffers from thermal fatigue, washcoat sintering, and matrix degradation. This deterioration frequently triggers persistent P0420 diagnostic trouble codes and causes internal ceramic blockages. A deteriorating substrate significantly increases exhaust backpressure against the cylinder head, restricting scavenging efficiency, choking high-RPM performance, increasing fuel consumption, and elevating combustion chamber temperatures.

The Engineering Solution

This direct-replacement catalytic converter features a heavy-gauge stainless steel outer shell designed to resist road salt corrosion and severe thermal cycling. Inside, a high-efficiency ceramic honeycomb monolith provides substantial surface area lined with a targeted precious-metal washcoat to facilitate complete chemical conversion of CO, HC, and NOx emissions. Designed as a 100% bolt-on assembly, it includes precision-machined OE-spec flanges and mounting hardware for immediate alignment with the stock exhaust routing without cutting or welding.
