Direct Fit Catalytic Con verter 04-06 Jeep 4.0L

The Direct Fit Catalytic Converter 04-06 Jeep 4.0L from AFE POWER is engineered for owners of 2004–2006 Jeep Wrangler TJ models running the legendary 4.0L inline-six engine who demand OEM-level performance without compromise. This direct-fit converter eliminates the guesswork of aftermarket installation while delivering cleaner emissions and restored exhaust efficiency. Whether you're tackling backcountry trails or running daily duty, a properly functioning catalytic converter ensures your Wrangler breathes freely and passes emissions testing without hassle.

Built from stainless steel construction in natural finish, this AFE POWER unit resists corrosion and thermal stress that typically degrade catalytic converters in harsh off-road and marine environments. The direct-fit design matches OEM mounting points precisely, allowing bolt-on installation without fabrication or custom hangers. Stainless steel substrate and coating maximize catalytic efficiency while maintaining durability through extreme temperature swings and moisture exposure common in boating and water-crossing applications. At 22 lbs, the converter integrates seamlessly into the factory exhaust architecture of the 4.0L TJ platform.

Jeep TJ owners running 2004–2006 model years with 4.0L engines benefit most from this replacement when original converters show signs of clogging, rattling internals, or failed emissions diagnostics. The direct-fit form factor eliminates guesswork during installation—no grinding, no welding required. Compatibility is exclusive to Jeep Wrangler TJ 4.0L inline-six engines during this production window; verify your model year and engine displacement before purchase. AFE POWER's stainless construction is ideal for vehicles frequently exposed to moisture, salt spray, or extended periods parked in humid storage.
