Cummins B6.7 DOC Filter 2022-2024: OEM 5418560

Reliable Exhaust Treatment for Cummins B6.7 Engines (2022–2024)

What is it?
The Diesel Oxidation Catalyst (DOC) filter for the Cummins B6.7 engine (model years 2022–2024) with OEM reference 5418560 is an essential emissions-control component. It converts hydrocarbons (HC) and carbon monoxide (CO) from the exhaust stream into cleaner, less harmful gases, helping the after-treatment system maintain steady, dependable operation.

Why choose this DOC Filter?
Engineered to meet original equipment specifications for the 2022–2024 B6.7 platform, this DOC filter is designed for precise fitment and compatibility. A worn, clogged, or mismatched component can lead to increased exhaust restriction, regeneration interruptions, or emissions-related fault codes. Installing the correct DOC filter helps restore clean exhaust flow and supports more consistent after-treatment behavior.

Key Benefits
✅ Converts HC and CO into cleaner exhaust output
✅ Supports the efficient function of downstream after-treatment components
✅ Helps maintain stable exhaust flow and reduce restriction
✅ Direct-fit design — no modifications required
✅ Built for heavy-duty, high-temperature operating environments

Applications
Ideal for medium-duty trucks, commercial vehicles, and equipment powered by Cummins B6.7 engines from model years 2022 through 2024, especially where emissions compliance and dependable system operation are crucial.

Installation Notes
Ensure the exhaust and after-treatment system has fully cooled before initiating service. Remove the existing DOC filter and examine the surrounding exhaust piping, sensors, and hardware for soot buildup or damage. Install the replacement using new clamps, gaskets, and seals. After installation, clear any stored emissions-system fault codes and verify proper exhaust-system behavior via diagnostic checks.

Final Thoughts
If your B6.7-equipped vehicle is showing signs of elevated exhaust restriction, frequent regeneration events, or emissions alerts, replacing the DOC filter with the correct OEM-specified unit is a practical step toward restoring clean, reliable exhaust flow. This component plays an important role in maintaining the integrity of the emissions-control system and supporting stable, dependable operation.
