Paccar MX11, MX13 DPF

Engine-Matched DPF for PACCAR MX11 & MX13 Engines

What is it?
The Paccar MX11, MX13 DPF is a Diesel Particulate Filter designed for PACCAR diesel engines, specifically the MX11 and MX13 models. A DPF is an emissions aftertreatment device that traps and holds soot (particulate matter) produced during combustion, preventing it from being released into the atmosphere as harmful smoke while the engine operates.

Why choose this DPF?
This Diesel Particulate Filter is engineered to align with PACCAR’s OEM standards for MX11 and MX13 engines, offering a direct replacement that matches original form, fit, and function. A properly functioning DPF helps maintain balanced exhaust flow and supports the engine’s emissions system, reducing the risk of particulate-related system alerts or uneven operation due to excessive buildup. 

Key Benefits
✅ Tailored for PACCAR MX11 and MX13 engines
✅ Captures and removes soot from diesel exhaust gases
✅ Supports consistent exhaust flow and reduced backpressure
✅ Direct-fit-style replacement — no custom modifications needed
✅ Helps maintain emissions-related system stability

Applications
This DPF is suitable for heavy-duty trucks and commercial vehicles equipped with PACCAR MX11 or MX13 diesel engines. Whether used in long-haul tractors, regional transport rigs, or vocational work trucks, the filter contributes to regulated emissions handling and helps keep exhaust conditioning in line with system requirements.

Installation Notes
Before servicing, fully cool the exhaust and aftertreatment components to avoid burns or damage. Remove the existing DPF and check surrounding connections, sensors, and mounting points for soot buildup or wear. Install the replacement filter using the proper gaskets and clamps for a secure, leak-free fit. After installation, clear any stored system codes and verify correct exhaust behavior using appropriate diagnostics.

Final Thoughts
A properly functioning Diesel Particulate Filter is vital to controlling particulate emissions and maintaining healthy exhaust flow in PACCAR MX11 and MX13 engines. If your vehicle is showing soot-related warnings, elevated backpressure, or uneven aftertreatment performance, replacing the DPF with a correctly matched unit can help restore stable exhaust conditioning and support reliable operation.
