Cummins B6.7 SCR Filter 2018-2024: OEM 5507928

Maintain Consistent NOx Control with the Cummins B6.7 SCR Filter

What is it?
The Selective Catalytic Reduction (SCR) filter for the Cummins B6.7 engine (model years 2018–2024), OEM reference 5507928, is an emissions-control component that plays a vital role in reducing nitrogen oxides (NOx) in the exhaust stream. As part of the aftertreatment system, it helps facilitate chemical reactions that convert NOx into less harmful compounds, supporting cleaner exhaust output.

Why choose this SCR Filter?
Engineered to meet original equipment specifications for the Cummins B6.7 platform, this SCR filter ensures proper fitment and dependable integration within the emissions system. A worn, blocked, or incorrect filter can lead to increased exhaust restriction, irregular regeneration cycles, or emissions-related fault codes. Installing the correct SCR filter helps maintain consistent exhaust flow and reliable aftertreatment performance.

Key Benefits
✅ Supports effective NOx reduction as part of the aftertreatment system
✅ Helps maintain proper exhaust flow and reduce restriction
✅ Direct-fit design — no modifications required
✅ Designed for heavy-duty, high-temperature operating environments
✅ Helps protect downstream SCR components and prolong system longevity

Applications
Ideal for medium-duty trucks, commercial vehicles, and equipment powered by Cummins B6.7 engines manufactured from 2018 through 2024. This SCR filter is particularly useful in fleet, vocational, and commercial applications where emissions compliance and consistent aftertreatment performance are essential.

Installation Notes
Before servicing, allow the exhaust and aftertreatment system to cool completely. Remove the existing SCR filter and inspect adjacent exhaust piping, sensors, and mounting hardware for soot accumulation, damage, or wear. Install the replacement using new clamps, gaskets, and seals. After installation, clear any emissions-system fault codes and verify proper system behavior through diagnostic checks.

Final Thoughts
If your B6.7-equipped vehicle is experiencing elevated exhaust restriction, emissions warnings, or irregular aftertreatment behavior, replacing the SCR filter with the correct OEM-specified unit is a practical step toward restoring consistent, dependable exhaust treatment. This component plays a key role in maintaining the integrity of your emissions-control system and supporting reliable equipment operation.
