Ford Powerstroke 6.7L DOC/DPF 2011-2012: OEM CC3Z-5H270-A

Support Complete Exhaust Filtration with a DOC/DPF Assembly for Ford Powerstroke 6.7L Engines

What is it?
The Ford Powerstroke 6.7L DOC/DPF assembly, identified by OEM CC3Z-5H270-A, is an integrated emissions aftertreatment component designed for Ford Powerstroke 6.7L diesel engines produced between 2011 and 2012. This assembly combines the Diesel Oxidation Catalyst (DOC) and Diesel Particulate Filter (DPF) into a single unit that works together to reduce harmful emissions by oxidizing exhaust gases and capturing soot particles before they exit the exhaust system.

Why choose this DOC/DPF Assembly?
Modern diesel emissions systems rely on both oxidation and particulate filtration to maintain clean exhaust flow and dependable aftertreatment performance. This DOC/DPF assembly is manufactured to match Ford Powerstroke 6.7L specifications, ensuring compatibility with factory-installed sensors, regeneration systems, and exhaust components. Over time, soot accumulation, ash buildup, catalyst degradation, and repeated regeneration cycles can reduce system efficiency, potentially causing increased exhaust restriction, regeneration issues, or emissions-related warning lights. Installing the correct OEM-matched assembly helps maintain reliable emissions processing and consistent exhaust system operation.

Key Benefits
✅ Designed for Ford Powerstroke 6.7L engines (2011–2012)
✅ Combines DOC and DPF functions into one integrated assembly
✅ Helps maintain efficient exhaust flow and soot filtration
✅ Direct-fit replacement for accurate installation
✅ Built for durability in demanding diesel operating conditions

Applications
This DOC/DPF assembly is used on Ford Super Duty trucks equipped with 6.7L Powerstroke diesel engines from 2011 through 2012. Common applications include F-250, F-350, F-450, and F-550 trucks used for towing, commercial service, fleet operations, and heavy-duty work where dependable emissions control is essential.

Installation Notes
Before installation, allow the exhaust and aftertreatment system to cool completely. Remove the existing DOC/DPF assembly and inspect surrounding sensors, pressure lines, clamps, and exhaust connections for contamination or wear. Install the replacement assembly using the appropriate mounting hardware and sealing components to ensure correct alignment and leak-free operation. After installation, verify proper regeneration performance and clear any stored fault codes using approved diagnostic equipment.

Final Thoughts
If your Ford Powerstroke 6.7L-powered truck is experiencing regeneration issues, increased exhaust backpressure, or emissions-related warning lights, replacing the DOC/DPF assembly with the correct OEM component can help maintain proper aftertreatment performance. The Ford Powerstroke 6.7L DOC/DPF assembly (OEM CC3Z-5H270-A) plays a vital role in supporting reliable emissions control, efficient exhaust filtration, and dependable truck operation.
