International Navistar MaxxForce 13 DOC Filter 2011-2014: OEM 5010813R91

Refine Emissions Control with International Navistar MaxxForce 13 DOC Filter 2011–2014 OEM 5010813R91

What is it?
The DOC Filter (OEM 5010813R91) for the International Navistar MaxxForce 13 engine is a critical emissions component designed to oxidize hydrocarbons (HC) and carbon monoxide (CO) in the exhaust stream. This process supports cleaner exhaust output and prepares gases for downstream after-treatment components.

Why choose this DOC Filter?
Built specifically for MaxxForce 13 engines from 2011–2014, this OEM DOC filter ensures correct fitment and dependable exhaust flow. A restricted or worn catalyst can lead to increased back-pressure, emissions fault codes, or unstable system operation. Installing the correct replacement helps restore proper exhaust system function.

Key Benefits
✅ Converts HC and CO into cleaner exhaust output
✅ Supports consistent operation of downstream after-treatment components
✅ Helps reduce exhaust restriction and back-pressure
✅ Direct-fit replacement with no modifications required
✅ Designed for heavy-duty use and high-temperature conditions

Applications
Ideal for on-highway trucks and vocational equipment powered by International Navistar MaxxForce 13 engines (2011–2014) where emissions compliance and system reliability are essential.

Installation Notes
Ensure the exhaust system is fully cooled before installation. Inspect the DOC housing, clamps, seals, and exhaust connections for soot buildup or wear. Replace gaskets and clamps as needed for a secure fit. After installation, clear diagnostic codes and verify proper exhaust flow and system operation.

Final Thoughts
If your MaxxForce 13 engine is experiencing exhaust restriction, emissions alerts, or inconsistent after-treatment behavior, the OEM 5010813R91 DOC Filter is the right solution. With precise fitment and durable construction, it helps your engine run cleaner, smoother, and more reliably.
