International Navistar MaxxForce 13 DOC Filter 2011-2014: OEM 5010844R1

Consistent Exhaust Treatment for Navistar MaxxForce 13 Engines

What is it?
The Diesel Oxidation Catalyst (DOC) for the International Navistar MaxxForce 13 engine (model years 2011–2014) is a core emissions-control component. It works by converting hydrocarbons (HC) and carbon monoxide (CO) in the exhaust stream into cleaner, less harmful gases, helping the aftertreatment system function reliably and efficiently.

Why choose this DOC?
Built to OEM specifications for the MaxxForce 13 platform, this DOC offers precise fitment and dependable exhaust-system compatibility. When a DOC becomes worn or restricted, it can contribute to increased exhaust resistance, irregular regeneration activity, or emissions-related fault codes. Installing the correct DOC helps maintain smooth exhaust flow and consistent system behavior.

Key Benefits
✅ Converts HC and CO into cleaner exhaust output
✅ Supports proper operation of downstream aftertreatment components
✅ Helps maintain steady exhaust flow and reduce restriction
✅ Direct-fit design matched to MaxxForce 13 specifications
✅ Constructed for heavy-duty, high-temperature operating environments

Applications
Designed for medium- and heavy-duty trucks and commercial vehicles powered by the International Navistar MaxxForce 13 engine from 2011 to 2014. This DOC is well suited for fleet and vocational applications where emissions compliance and dependable system operation are essential.

Installation Notes
Allow the exhaust and aftertreatment system to cool completely before servicing. Remove the existing DOC and inspect the housing, clamps, and adjacent exhaust piping for buildup, cracks, or damage. Install the replacement using new gaskets, seals, and clamps. After installation, clear any stored emissions fault codes and confirm proper exhaust-system behavior using diagnostic checks.

Final Thoughts
If your MaxxForce 13-equipped vehicle is experiencing emissions alerts, increased exhaust restriction, or inconsistent aftertreatment activity, replacing the DOC with a properly matched OEM-spec unit is a practical step toward restoring clean, reliable exhaust flow. This component plays a vital role in maintaining the overall integrity of your emissions-control system and supporting dependable operation.
