Cummins B6.7 SCR Filter 2022-2024: OEM 5418533

Maintain Efficient Aftertreatment with the Cummins B6.7 SCR Filter

What is it?
The Selective Catalytic Reduction (SCR) filter for the Cummins B6.7 engine (model years 2022–2024), OEM reference 5418533, is an emissions-control component designed to support the reduction of nitrogen oxides (NOx) in the exhaust stream. Working as part of the aftertreatment system, it helps facilitate the chemical reactions necessary for cleaner exhaust emissions.

Why choose this SCR Filter?
Built to match original equipment specifications for the 2022–2024 B6.7 platform, this SCR filter ensures proper fitment and reliable integration within the emissions system. A worn, clogged, or mismatched filter can lead to higher exhaust restriction, irregular regeneration cycles, and emissions-related fault codes. Installing the correct SCR filter helps maintain steady aftertreatment function and consistent exhaust-system behavior.

Key Benefits
✅ Supports 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 prolong the life of downstream SCR components

Applications
Ideal for medium-duty trucks, commercial vehicles, and equipment powered by Cummins B6.7 engines (2022–2024) where emissions compliance and reliable aftertreatment performance are essential.

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

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