Paccar PX6 DPF 2011-2013

Clean Particulate Control for PX6 Engines – Paccar PX6 DPF (2011–2013)

What is it?
The Paccar PX6 DPF (2011–2013) is a factory‑spec Diesel Particulate Filter designed for Paccar PX6 / Cummins ISB engines in model years 2011 to 2013. Its core function is to trap soot and other fine particles from exhaust gases, then periodically regenerate by oxidizing or burning off the accumulated soot to maintain filtration capacity.

Why choose this OEM DPF?
This DPF unit is built to Paccar/Cummins original engineering standards—matching material quality, flow resistance, thermal tolerance, and structural integrity. Choosing the OEM or an OEM‑level unit helps avoid issues such as excessive backpressure, inefficient regeneration, diagnostic fault codes, or premature failure that often occur with non‑spec or undersized filters.

Key Benefits
 ✅ Drop‑in compatibility for PX6 / ISB engines (2011–2013)
 ✅ Efficient soot capture and regeneration support
 ✅ Maintains proper exhaust flow and backpressure balance
 ✅ Durable design for high-temperature, extended duty use
 ✅ Fully compatible with factory emission systems and sensor calibration

Applications
This DPF is used in Paccar / PX6‑powered trucks, medium-duty applications, and equipment during the 2011–2013 engine generation. It’s a critical component of the exhaust aftertreatment train—serving in vocational, transport, and fleet vehicles where particulate control is required.

Installation Notes
Installation should be performed by a trained technician. First, allow the exhaust system to cool completely. Remove the old DPF carefully, preserving sensor wiring and minimizing debris intrusion. Clean and inspect mating flange surfaces, replacing gaskets or seals as needed. Align and mount the new DPF, torquing fasteners to OEM specifications. After installation, verify there are no exhaust leaks, ensure unobstructed flow, and clear any emission‑related codes via diagnostics to confirm the system restores proper operation.

Final Thoughts
If your PX6 has active DPF faults, reduced performance, or high backpressure alerts, replacing the DPF with this factory‑matched unit restores particulate filtration integrity. With OEM‑level fit and durability, it keeps your engine compliant, efficient, and reliable on the road.
