Advanced Oxidation Catalyst for Cummins ISX Engines (2008–2010)
What is it?
The Cummins ISX DOC (Diesel Oxidation Catalyst) for 2008–2010 is a pivotal emissions component that chemically transforms carbon monoxide (CO) and unburned hydrocarbons (HC) into less harmful compounds before they enter downstream emission systems.
Why choose this DOC?
Calibrated specifically for ISX engines produced between 2008 and 2010, this DOC ensures efficient oxidation while maintaining appropriate exhaust flow. Using the correct unit helps protect downstream filters or catalysts, avoid backpressure issues, and reduce the likelihood of diagnostic faults tied to incompatible or inferior parts.
Key Benefits
✅ Matched for Cummins ISX (2008–2010)
✅ Converts CO and hydrocarbons into safer exhaust gases
✅ Prepares emissions output for subsequent filters or catalysts
✅ Rugged construction tolerates high thermal stress
✅ Direct-fit design facilitates accurate installation
Applications
Ideal for heavy-duty trucks, commercial fleets, or industrial equipment powered by ISX engines in the 2008–2010 span. This DOC functions as the first catalytic step in your emission control train.
Installation Notes
Work only after the engine and exhaust are fully cooled. Remove the existing DOC and inspect adjacent piping, flanges, sensors, and seals for wear or damage. Mount the replacement with new gaskets, torque all fasteners to Cummins specs, and verify sealing integrity. After installation, restore any cleared fault codes and run a test or regeneration cycle to confirm proper function.
Final Thoughts
For your ISX engine, this DOC offers the performance, durability, and compatibility needed to support a clean, efficient emissions strategy from the ground up.
