Catalytic Converter for Ford Flex Taurus (2013-2019) 3.5L Front Left & Right

Direct-Replacement Manifold Catalytic Converter Pair for 2013-2019 Ford Flex & Taurus (D3/D4)

What it Does: The manifold catalytic converter set replaces deteriorated front exhaust catalysts on the 2013-2019 Ford Flex and Taurus to eliminate P0420/P0430 diagnostic trouble codes and restore proper exhaust scavenging.

The Stock Ford Flex & Taurus Catalyst Failure Point

Factory exhaust manifolds on the transverse **D3/D4** platform are subjected to severe thermal cycling due to tightly packaged engine bay constraints. Over time, the internal ceramic monolith substrate in the factory converters experiences washcoat degradation, core sintering, and thermal shock fractures. This deterioration reduces exhaust flow velocity, creates elevated backpressure against the **Duratec 35** cylinder heads, and triggers persistent check engine lights for catalyst system efficiency below threshold (P0420 and P0430).

The Engineering Solution

Engineered as a bolt-on solution for Bank 1 and Bank 2 exhaust banks, these direct-replacement converters feature heavy-gauge stainless steel tubing with robotic TIG welds for structural integrity under high exhaust gas temperatures. The high-efficiency ceramic honeycomb cores provide optimal precious metal washcoat dispersion, ensuring swift light-off times and proper reduction of HC, CO, and NOx without restricting flow. Thick OE-spec laser-cut flanges match factory port geometry perfectly, guaranteeing a leak-free seal to standard cylinder heads and intermediate flex pipes.
