Catalytic Converter for Ford Bronco II (1988-1990) 2.9L

Direct-Fit EPA Catalytic Converter for 1988-1990 Ford Bronco II (Bronco II Platform)

What it Does: The direct-fit catalytic converter replaces the depleted or restricted factory emissions unit on the 1988-1990 Ford Bronco II to restore exhaust gas velocity and eliminate diagnostic trouble codes.

The Stock Ford Bronco II Catalyst Degradation

After decades of thermal cycling, the factory ceramic monolith inside the stock catalytic converter suffers from washcoat depletion, sintering, and physical core fracture. On the Ford Bronco II, unburned hydrocarbons and oil blow-by poison the active precious metals, causing severe exhaust backpressure, lost low-end torque, rotten-egg odors, and active P0420 catalyst efficiency fault codes.

The Engineering Solution

Engineered as a bolt-in replacement for OEM part 44806, this converter features a heavy-gauge, corrosion-resistant stainless steel outer shell encasing a high-flow ceramic honeycomb substrate. The optimized cell density promotes efficient catalytic reduction of NOx, CO, and HC without choking exhaust scavenging on the 2.9L Cologne V6 engine. Precision-formed inlet and outlet flanges match factory exhaust pipe alignments for a leak-free mechanical seal without custom pipe bending.
