What is it?
The Caterpillar C13 DOC Filter (OEM 390-0696) is a Diesel Oxidation Catalyst designed for C13 engines produced between 2015 and 2022. It helps reduce carbon monoxide (CO) and unburned hydrocarbons (HC) in the exhaust before gases reach downstream emissions components.
Why choose OEM 390-0696?
Made to Caterpillar’s precise specifications, this DOC filter ensures proper conversion behavior and exhaust flow characteristics. Using the OEM unit helps you avoid issues like restricted airflow, inefficient oxidation, or compatibility problems that may occur with generic replacements.
Key Benefits
✅ Engineered for Caterpillar C13 engines (2015–2022)
✅ Converts CO and hydrocarbons into safer emissions gases
✅ Helps protect downstream aftertreatment systems
✅ Built to endure high exhaust temperatures and continuous use
✅ Direct-fit design for precise and hassle-free installation
Applications
This DOC filter fits heavy-duty trucks, construction machines, and industrial equipment powered by Caterpillar C13 engines from 2015 through 2022. It supports cleaner exhaust performance and helps maintain system balance in demanding operating environments.
Installation Notes
Make sure the engine and exhaust system are completely cooled before starting installation. Remove the existing DOC filter and inspect connecting pipes, flanges, and seals for wear or damage. Install the new filter with fresh gaskets, torque all fasteners to Caterpillar specifications, and confirm proper sealing. After installation, run diagnostics or monitor exhaust behavior to verify correct function.
Final Thoughts
For a well-matched catalytic component in your exhaust system, the OEM 390-0696 DOC Filter delivers the fit, performance, and durability your Caterpillar C13 engine needs to support a healthy aftertreatment path.
