Cummins ISC DOC 2008-2010

Recover Emission Control with the OEM ISC DOC (2008–2010)

What is it?
The ISC DOC (Diesel Oxidation Catalyst) for Cummins ISC engines from 2008 to 2010 oxidizes hydrocarbons (HC) and carbon monoxide (CO) in exhaust emissions before they reach downstream treatment components.

Why choose this OEM DOC?
This DOC is engineered to Cummins’ original specifications—matching exhaust flow, backpressure, material endurance, and system integration. A proper OEM or OEM-matched unit helps prevent diagnostic faults, pressure issues, or early failure that might result from mismatched aftermarket parts.

Key Benefits
 ✅ Direct‐fit for Cummins ISC (2008–2010)
 ✅ Effective oxidation of HC and CO
 ✅ Maintains proper exhaust flow and prevents excessive backpressure
 ✅ Built to endure harsh, high-temperature exhaust conditions
 ✅ Compatible with factory emissions control systems and sensors

Applications
Used in medium-duty trucks, utility vehicles, and equipment powered by Cummins ISC engines in model years 2008 through 2010. It’s part of the engine’s emission aftertreatment system to reduce pollutants in exhaust gas.

Installation Notes
Installation should be done by a qualified technician. First, allow the exhaust system to cool. Remove the old DOC, avoiding damage to surrounding piping or sensors. Clean all mating surfaces thoroughly and replace gaskets or seals where needed. Install the replacement DOC with proper alignment and torque per Cummins’ specifications. After installation, inspect for leaks, confirm exhaust flow is unobstructed, and clear any emission or fault codes using diagnostic tools.

Final Thoughts
If your ISC engine is showing emission warnings, increased smoke, or performance decline, replacing the DOC with this correct 2008–2010 version helps restore proper oxidation and emission control. It supports the entire aftertreatment chain and helps ensure cleaner and more reliable operation.
