Cummins ISB 6.7 DPF ISB 6.7 2011-2013

Bring Emission Control Back to Spec – Cummins ISB 6.7 DPF (2011‑2013)

What is it?
The DPF (Diesel Particulate Filter) for Cummins ISB 6.7 engines from model years 2011 to 2013 captures soot and particulate emissions in the exhaust stream. During regeneration, trapped particulates are oxidized, reducing emissions output and maintaining compliance with emission standards.

Why choose this OEM DPF?
This genuine DPF is built to Cummins’ original specifications—ensuring proper filter media, flow characteristics, structural strength, and thermal resilience. A factory-matched unit helps avoid issues like excessive backpressure, sensor misdiagnosis, or shortened life seen with off-spec replacements.

Key Benefits
 ✅ Drop-in fit for Cummins ISB 6.7 (2011–2013)
 ✅ Effective capture and oxidation of soot during regeneration
 ✅ Maintains correct exhaust flow and limits pressure buildup
 ✅ Durable construction to handle high-temperature cycles
 ✅ Compatible with factory emission sensors and diagnostics

Applications
Used in medium-duty trucks, vocational rigs, buses, and specialty equipment powered by the ISB 6.7L engine in the 2011–2013 range. The DPF is critical in the aftertreatment train to ensure particulate emissions stay within regulated limits under all operating conditions.

Installation Notes
Installation should be carried out by a certified technician. First, allow the exhaust system to cool completely. Remove the existing DPF carefully, preserving sensor wiring. Clean mating surfaces and inspect for damage. Replace gaskets or seals, align the new DPF in place, and torque fasteners to Cummins’ specification. After installation, check for exhaust leaks, confirm exhaust flow is unobstructed, and clear any emission or DPF fault codes using diagnostic tools.

Final Thoughts
If your ISB 6.7 is showing DPF fault codes, performance loss, or high backpressure warnings, installing the correct DPF for 2011–2013 restores particulate control and exhaust system health. With factory-level compatibility and design, it helps your engine run cleaner, more reliably, and compliant.
