Direct-Fit Front & Rear Catalytic Converter Set for 2002-2003 Ford Explorer Sport (UN105)

What it Does: The Front & Rear Catalytic Converter assembly replaces deteriorated factory emissions units on the 2002-2003 Ford Explorer Sport to clear check engine lights, normalize exhaust backpressure, and restore emissions compliance.

The Stock Ford Explorer Sport Catalytic Converter Degradation

The factory catalytic converters on the UN105 chassis suffer from thermal fatigue and substrate breakdown over high-mileage heat cycles. On the high-compression Cologne 4.0L SOHC V6, rich-running conditions, unburned hydrocarbons, and aging upstream oxygen sensors frequently lead to core sintering and washcoat contamination. This substrate melt-down restricts exhaust scavenging, elevates backpressure at the manifolds, triggers persistent P0420 and P0430 DTC codes, and chokes off engine power during hill climbs or towing.

The Engineering Solution

This comprehensive front and rear converter kit delivers a bolt-in replacement built from corrosion-resistant stainless steel tubing. Featuring a high-efficiency ceramic honeycomb monolith wash-coated with noble metal catalysts, it ensures optimal cross-sectional flow while maintaining thorough chemical conversion of CO, HC, and NOx. Precision-machined, heavy-gauge mating flanges and factory-located downstream O2 sensor bungs eliminate the need for cutting, custom fabrication, or MIG welding. Mandrel-bent transition cones maintain continuous gas velocity across both banks to protect the exhaust valves from thermal backup.
