Clean Up Exhaust Performance with International Navistar MaxxForce 13 DOC Filter 2011–2014 OEM 5010812R91
What is it?
The DOC Filter (OEM 5010812R91) for the International Navistar MaxxForce 13 engine (2011–2014) is a key emissions-control component. It oxidizes hydrocarbons (HC) and carbon monoxide (CO) in the exhaust, helping reduce harmful emissions and prepare gases for downstream treatment.
Why choose this DOC Filter?
Designed specifically for MaxxForce 13 engines built between 2011 and 2014, this OEM filter offers the correct fit and reliable performance. A clogged or deteriorated catalyst can increase back-pressure, disrupt regeneration cycles, and trigger emissions fault codes. Replacing it with the right part promotes improved exhaust flow and system stability.
Key Benefits
✅ Converts HC and CO into cleaner exhaust output
✅ Supports proper downstream after-treatment function
✅ Helps reduce back-pressure and exhaust restriction
✅ Direct-fit replacement—no modifications required
✅ Built for heavy-duty service and high-temperature environments
Applications
Ideal for commercial trucks and vocational equipment equipped with the Navistar MaxxForce 13 engine (2011–2014) where emissions control and system reliability are essential.
Installation Notes
Before servicing, let the exhaust system cool completely. Inspect the DOC housing and related exhaust connections for damage or soot buildup. Replace all seals, gaskets, and clamps to ensure a secure fit. After installation, clear any fault codes and verify correct regeneration behavior and exhaust flow via diagnostics.
Final Thoughts
If your MaxxForce 13 engine is showing signs of elevated back-pressure, frequent after-treatment fault codes, or restricted exhaust flow, installing the correct DOC Filter is the solution. With accurate fitment and rugged construction, this part helps your engine run cleaner, smoother, and more reliably.
