Refine Exhaust Emissions with Detroit DD15 DD13 DOC Filter 2008–2010 OEM A6804901214
What is it?
The DOC Filter (OEM A6804901214) for Detroit DD15 and DD13 engines (2008–2010) is a vital emissions-control component. It oxidizes hydrocarbons (HC) and carbon monoxide (CO) in the exhaust stream, helping your after-treatment system operate effectively and supporting cleaner, more efficient exhaust flow.
Why choose this DOC Filter?
Built specifically for the 2008–2010 Detroit DD15 and DD13 platforms, this OEM filter delivers correct fitment and dependable performance. A worn or restricted catalyst can cause higher back-pressure, frequent regenerations, lost fuel economy, and emissions fault codes. Replacing it with the right DOC helps return your system to proper operation.
Key Benefits
✅ Converts HC and CO into cleaner exhaust output
✅ Supports downstream DPF and SCR system components
✅ Helps reduce exhaust restriction and back-pressure
✅ Direct-fit design—no modifications required
✅ Designed for heavy-duty service and high-temperature use
Applications
Ideal for freight trucks and heavy equipment powered by Detroit DD15 or DD13 engines (2008–2010) where emissions compliance, reliability, and system performance are essential.
Installation Notes
Before installation, make sure the exhaust system is completely cool. Inspect the DOC housing, exhaust connections, clamps, and seals for soot buildup or wear. Replace all necessary gaskets and clamps to ensure a secure, leak-free fit. After installation, clear any diagnostic codes and monitor exhaust behavior to confirm proper performance.
Final Thoughts
If your truck is showing increased back-pressure, frequent after-treatment faults, or reduced exhaust performance, the OEM A6804901214 DOC Filter is the correct replacement. With accurate fitment and rugged build quality, this part helps your engine run cleaner, smoother, and more reliably.
