Mack MP8, MP10 DOC 2011-2013

Built for Emission Balance: Mack MP8, MP10 DOC (2011–2013)

What is it?
The Mack MP8, MP10 DOC (2011–2013) is a Diesel Oxidation Catalyst crafted for Mack’s MP8 and MP10 engines in the 2011–2013 model years. It works to convert leftover hydrocarbons (HC) and carbon monoxide (CO) in the exhaust into less harmful gases before they exit the tailpipe.

Why Choose the Mack MP8, MP10 DOC (2011–2013)?
This DOC is engineered to mirror the original exhaust architecture: flange design, sensor ports, and internal flow paths are all matched to OEM specifications. That means fewer surprises during installation, better compatibility with the rest of your emission system, and lasting, stable operation.

Key Benefits
✅ OEM Fitment: Aligns with factory mounting and exhaust paths for smooth installation
✅ Robust Construction: Made to handle high heat, vibration, and continuous exhaust exposure
✅ Cleaner Exhaust Output: Accelerates oxidation of HC and CO to lower emissions
✅ Operational Stability: Helps reduce fault codes and maintain steady exhaust behavior
✅ Protects Exhaust Components: Cleaner exhaust helps prolong the life of sensors, downstream catalysts, and filters

Applications
This DOC is ideal for Mack trucks and heavy-duty vehicles powered by MP8 or MP10 engines made between 2011 and 2013. It performs well in highway, regional, and vocational settings where emissions performance and system durability are essential.

Installation Notes
Though designed for direct replacement, professional installation is strongly advised. Ensure all clamps, gaskets, and sensor connections are correctly mounted, sealed, and aligned. After installation, reset diagnostics and verify that your engine control unit recognizes the new catalyst.

Final Thoughts
Emissions control is only as good as the parts in your exhaust chain. The Mack MP8, MP10 DOC (2011–2013) provides an OEM-level solution to restore proper oxidation chemistry and support reliable, compliant operation over the long haul.
