Cummins X15 DOC Filter 2022-2024: OEM 5509696

Precision Exhaust Conditioning for Cummins X15 Engines (2022–2024)

What is it?
The Diesel Oxidation Catalyst (DOC) filter for Cummins X15 engines covering model years 2022–2024, identified by OEM part number 5509696, is a key aftertreatment component. It begins the process of converting hydrocarbons (HC) and carbon monoxide (CO) in exhaust gases into less harmful byproducts before the gases continue through the rest of the emissions system, helping sustain coordinated emissions control.

Why choose this DOC Filter?
Designed to meet the original specifications for Cummins X15 engines, this DOC filter provides exact fitment and dependable integration within the aftertreatment assembly. Over time, DOC filters can become restricted or worn, which may disrupt proper exhaust flow and contribute to emissions system alerts or irregular behavior. Selecting the correct OEM-specified DOC filter supports stable exhaust conditioning and predictable aftertreatment system responses.

Key Benefits
✅ Specifically engineered for Cummins X15 aftertreatment setups
✅ Conditions exhaust gases prior to downstream treatment elements
✅ Helps support consistent exhaust flow patterns
✅ Direct-fit design with no modifications required
✅ Constructed to handle high temperatures and rigorous operating conditions

Applications
This DOC filter is ideal for heavy-duty trucks and commercial vehicles powered by Cummins X15 engines produced between 2022 and 2024. Common applications include long-haul tractors, regional transport units, vocational rigs, and other equipment where dependable emissions control and coordinated aftertreatment behavior are essential.

Installation Notes
Before servicing, allow the exhaust and aftertreatment system to cool completely. Remove the existing DOC filter and inspect surrounding exhaust piping, mounting hardware, and sensors for soot buildup or damage. Install the replacement DOC filter using fresh gaskets, clamps, and seals to ensure proper sealing. After installation, clear any stored system codes and verify correct exhaust system behavior with diagnostic tools.

Final Thoughts
If your Cummins X15-equipped vehicle shows signs of restricted exhaust flow or unexpected emissions alerts, replacing the DOC filter with the correct OEM-specified unit can help restore balanced exhaust conditioning. The Cummins X15 DOC Filter (OEM 5509696) plays a vital role in maintaining emissions system integrity and supporting dependable vehicle operation.
