International Navistar MaxxForce 13 DOC Filter 2011-2014: OEM 5013252R1

Dependable Emissions Control for MaxxForce 13 Applications

What is it?
The Diesel Oxidation Catalyst (DOC) for the International Navistar MaxxForce 13 engine (model years 2011–2014) is a vital emissions-control component. It converts hydrocarbons (HC) and carbon monoxide (CO) in the exhaust stream into cleaner, less harmful gases, supporting consistent exhaust treatment and stable aftertreatment operation.

Why choose this DOC?
Manufactured to OEM specifications for the MaxxForce 13 platform, this DOC ensures proper fitment and reliable compatibility with the factory exhaust system. A worn or restricted catalyst can contribute to elevated exhaust resistance, irregular regeneration behavior, or emissions-related fault codes. Installing the correct DOC helps maintain clean exhaust flow and dependable system behavior.

Key Benefits
✅ Converts HC and CO into cleaner exhaust output
✅ Supports the proper function of downstream aftertreatment components
✅ Helps maintain steady exhaust flow and minimize restriction
✅ Direct-fit design aligned with MaxxForce 13 specifications
✅ Built for heavy-duty, high-temperature operating environments

Applications
Designed for medium- and heavy-duty trucks and commercial vehicles equipped with the International Navistar MaxxForce 13 engine from 2011 to 2014. This DOC is well suited for fleet, vocational, and long-haul applications where emissions compliance and consistent system operation are critical.

Installation Notes
Allow the exhaust and aftertreatment system to cool fully before beginning service. Inspect the existing DOC, mounting hardware, and surrounding exhaust components for buildup, cracks, or damage. Install the replacement using new clamps, gaskets, and seals. After installation, clear any stored emissions fault codes and verify proper exhaust-system operation using diagnostic checks.

Final Thoughts
If your MaxxForce 13-equipped vehicle is experiencing emissions warnings, increased exhaust restriction, or inconsistent aftertreatment behavior, replacing the DOC with a properly matched OEM-spec unit is a practical way to restore clean, reliable exhaust treatment. This component plays an essential role in maintaining emissions system integrity and supporting dependable day-to-day operation.
