Catalytic Converter for Lincoln MKX (2007-2010) 3.5L

Direct-Fit Stainless Steel Catalytic Converter for 2007-2010 Lincoln MKX

What it Does: Restores exhaust scavenging efficiency and eliminates P0420/P0430 DTC catalyst efficiency codes on the rear/right bank of the 3.5L Duratec V6 powertrain.

The Stock MKX Catalyst Degradation

The factory rear manifold and bank-specific exhaust plumbing on the CD3 platform subject the catalytic converter to intense thermal cycling and backpressure accumulation. Over time, internal washcoat breakdown and carbon fouling lead to clogged ceramic honeycomb cells. This substrate degeneration restricts exhaust gas velocity, increases cylinder head temperatures, triggers check engine lights, and compromises both mid-range torque and fuel economy.

The Engineering Solution

Engineered as an exact bolt-on assembly, this converter features a heavy-duty stainless steel outer shell designed to resist road debris and thermal fatigue. Inside, a high-efficiency ceramic honeycomb washcoat maximizes surface area contact to clean unburnt hydrocarbons and NOx without bottlenecking exhaust pulses. Precision-welded direct-fit flanges mate flush to stock mating surfaces, utilizing the included hardware and gaskets to prevent blow-by leaks.
