Advanced Oxidation Catalyst for Cummins ISX (2008–2010)
What is it?
The Cummins ISX DOC (Diesel Oxidation Catalyst) for 2008–2010 is a specialized emissions component that converts carbon monoxide (CO) and unburned hydrocarbons (HC) in the exhaust into cleaner gases before they reach further treatment stages.
Why choose this DOC?
Tailored for ISX engines from 2008 to 2010, this DOC ensures reliable oxidation without disrupting exhaust flow. Selecting the correct unit helps protect downstream components, avoid excess backpressure, and reduce the likelihood of fault codes from mismatched parts.
Key Benefits
✅ Calibrated for Cummins ISX engines (2008–2010)
✅ Converts CO and hydrocarbons into safer emissions
✅ Supports downstream DPF or SCR systems by preparing exhaust gases
✅ Built to endure high temperatures and continuous use
✅ Direct-fit design ensures precise installation
Applications
Ideal for heavy trucks, buses, and industrial applications powered by Cummins ISX engines built between 2008 and 2010. It serves as the first catalytic stage in the emission control path.
Installation Notes
Ensure the engine and exhaust are fully cooled. Remove the old DOC, inspect adjacent pipes, flanges, sensors, and seals for wear or damage, and install the new unit using fresh gaskets. Torque hardware to Cummins specifications and verify all seals. After installation, clear fault codes and run a drive or regeneration cycle to confirm proper function.
Final Thoughts
If your ISX engine requires a dependable oxidation stage, this DOC offers the performance, durability, and correct engineering to back your emissions system reliably.
