Direct Fit Catalytic Con verter 04-06 Jeep 4.0L

The Direct Fit Catalytic Converter 04-06 Jeep 4.0L from AFE POWER is designed as a direct replacement for stock catalytic converters in 2004–2006 Jeep models equipped with the 4.0L inline-six engine. This product is ideal for Jeep owners facing emissions restrictions or degradation of their factory converters, ensuring compliance with performance expectations and emissions standards.

Constructed with a ceramic substrate and a precious-metal catalyst matrix, this catalytic converter effectively oxidizes unburned hydrocarbons and carbon monoxide while reducing nitrogen oxides. Its high-flow design minimizes backpressure compared to restrictive OEM units, which can enhance throttle response and fuel economy while meeting or exceeding Clean Air Act compliance thresholds. The robust internal baffling is engineered to withstand the thermal cycling associated with off-road driving and extended highway use.

Jeep 4.0L owners will find significant benefits from this direct-fit solution, which integrates seamlessly into the factory exhaust system without the need for custom fabrication or re-routing. The 22-pound assembly maintains bolt-on compatibility, preserving the original exhaust manifold-to-muffler architecture. This ensures a straightforward installation process, making it an excellent choice for those looking to replace their catalytic converter efficiently.
