Catalytic Converter for Dodge Grand Caravan (2008-2010) 3.3L/3.8L

Direct-Fit Replacement Catalytic Converter for 2008-2010 Dodge Grand Caravan (RT)

What it Does: The catalytic converter replaces the degraded factory emissions unit on the 2008-2010 Dodge Grand Caravan to clear P0420/P0430 fault codes, normalize exhaust backpressure, and restore proper tailpipe emissions.

The Stock Dodge Grand Caravan Catalyst Deterioration

Factory catalytic converters on the RT chassis Grand Caravan paired with EGA (3.3L) and EGH (3.8L) pushrod engines frequently succumb to internal substrate erosion and thermal fatigue over high mileage. Unburned hydrocarbons and persistent thermal cycling cause catalyst washcoat sintering, diminishing the precious metal conversion surface. This degradation triggers recurring check engine lights, restricts exhaust scavenging, elevates engine bay temperatures, and causes failure during mandatory OBD II readiness monitor tests.

The Engineering Solution

This replacement converter utilizes a durable stainless steel outer body and heavy-gauge tubing engineered to resist corrosion and thermal deformation. The core features a high-efficiency ceramic honeycomb substrate layered with a targeted precious metal washcoat to effectively oxidize carbon monoxide and unburnt fuel while reducing nitrogen oxides. Manufactured with a CNC-formed 4-bolt welded flange, precise downstream pipe outlet, and factory-placed oxygen sensor bungs, this unit replaces OEM interchange numbers 233635, 324847, and 643032 without requiring cutting or custom welding.
