Navistar N13 DOC

Reliable Emissions Control for the Navistar N13 Engine

What is it?
The Diesel Oxidation Catalyst (DOC) for the Navistar N13 engine is a critical emissions-control component. It converts hydrocarbons (HC) and carbon monoxide (CO) from the exhaust stream into cleaner gases, helping to ensure that downstream after-treatment elements operate under optimal conditions.

Why choose this DOC?
Designed specifically for the Navistar N13 platform (2011-2013 model years), this DOC provides correct fitment and dependable functionality within the system. A deteriorated or clogged catalyst may increase exhaust resistance, trigger more frequent regeneration cycles, or generate emissions-related fault codes. Installing the properly matched DOC helps support smooth exhaust flow and stable system behavior. 

Key Benefits
✅ Converts HC and CO into cleaner exhaust output
✅ Prepares exhaust flow for downstream after-treatment components
✅ Helps maintain steady exhaust flow and reduce restriction
✅ Direct-fit design tailored to Navistar N13 applications
✅ Built to handle heavy-duty operating conditions and high exhaust temperatures

Applications
This DOC is ideal for medium- and heavy-duty trucks and equipment powered by the Navistar N13 engine (2011-2013). It is especially suited for fleet operations where emissions compliance and reliable system functionality are essential.

Installation Notes
Allow the exhaust and after-treatment system to cool fully before servicing. Remove the existing DOC, inspect the housing and adjacent exhaust piping for buildup or damage. Install using new clamps, gaskets, and seals. After installation, clear emissions fault codes and verify system performance through diagnostics.

Final Thoughts
If your N13-equipped vehicle is showing signs of elevated exhaust restriction, frequent regenerations, or inconsistent after-treatment behavior, replacing the DOC with the correct application-specific unit is a practical step toward restoring clean, reliable exhaust flow and dependable emissions system performance.
