Keep Your Fleet Running Clean: Paccar MX13 DOC (2011–2013)
What is it?
The Paccar MX13 Diesel Oxidation Catalyst (DOC) for 2011–2013 engines is a vital emissions component that converts carbon monoxide (CO) and unburned hydrocarbons (HC) into cleaner gases before they reach downstream systems like the DPF or SCR.
Why choose this DOC?
Engineered exclusively for MX13 engines built between 2011 and 2013, this DOC delivers efficient oxidation performance while maintaining smooth exhaust flow. Using the proper fit helps prevent excess backpressure, protects downstream parts, and avoids system errors that can arise from incompatible replacements.
Key Benefits
✅ Precisely designed for Paccar MX13 engines (2011–2013)
✅ Converts CO and hydrocarbons into environmentally safer exhaust gases
✅ Enhances efficiency of downstream DPF or SCR components
✅ Built for high heat, vibration, and heavy-duty conditions
✅ Direct-fit design ensures quick and accurate installation
Applications
Perfect for heavy trucks, commercial fleets, and industrial equipment running Paccar MX13 engines from 2011–2013. This DOC serves as the first stage of the emission control system, ensuring cleaner exhaust and reliable engine performance.
Installation Notes
Allow the engine and exhaust system to cool completely before working. Remove the old DOC and inspect adjoining pipes, sensors, and seals for damage or wear. Install the new DOC with fresh gaskets, torque all fasteners to Paccar specifications, and confirm proper sealing. Once installed, clear any diagnostic codes and perform a regeneration or drive cycle to verify proper operation.
Final Thoughts
For Paccar MX13 engines, this DOC delivers dependable emissions performance, exceptional durability, and the precision fit you need to keep your truck clean, compliant, and road-ready.
