Catalytic Converter for Mitsubishi Eclipse (2006-2012) 2.4L

Direct-Fit Catalytic Converter for 2006-2012 Mitsubishi Eclipse

Direct-fit emissions replacement: Restores exhaust scavenging dynamics and catalytic conversion efficiency to resolve persistent P0420 diagnostic trouble codes on 2.4L 4G69 powertrains.

The Stock Eclipse Substrate Deterioration

Continuous thermal cycling and extended mileage degrade the factory front catalytic converter on the 4G-chassis Eclipse. Internal ceramic monoliths suffer washcoat loss, substrate crumbling, or soot glazing from continuous stoichiometric fluctuations. This structural breakdown increases exhaust backpressure, restricts exhaust evacuation during valve overlap cycles, dulls mid-range throttle response, and fails tailpipe emissions compliance.

The Engineering Solution

Engineered as a bolt-on assembly, this unit features a heavy-gauge stainless steel casing coupled to a high-surface-area ceramic substrate. The specialized washcoat provides active catalytic reduction of hydrocarbons, carbon monoxide, and oxides of nitrogen without impeding volumetric flow. Thick, warp-resistant mounting flanges ensure positive sealing against heat distortion, while factory-located oxygen sensor bungs maintain standard sensor reach and wiring geometry for seamless, fabrication-free installation.
