Emission Protection Upgrade: Cummins B6.7 / L9 DPF (2018–2022)
What is it?
The Cummins B6.7 / L9 DPF (Diesel Particulate Filter) for model years 2018–2022 is a key component in your engine’s emissions system. It captures soot and particulate pollutants from exhaust gases, helping to reduce emissions and protect downstream aftertreatment components.
Why choose the correct DPF?
This DPF is engineered specifically for B6.7 / L9 engines of the 2018–2022 period. Using an improper or mismatched DPF can lead to excessive backpressure, forced regenerations, or emissions faults. Choosing the right DPF helps maintain system balance and performance across your exhaust system.
Key Benefits
✅ Designed for Cummins B6.7 and L9 engines (2018–2022)
✅ Efficiently traps soot and particulate emissions
✅ Helps reduce engine derates, fault codes, and costly damage
✅ Built to endure extreme temperatures and exhaust conditions
✅ Direct-fit installation for seamless integration into existing systems
Applications
This DPF is ideal for medium-duty trucks, buses, generators, and equipment running Cummins B6.7 or L9 engines built between 2018 and 2022. It ensures consistent emissions control in systems that include DOC, SCR, or other aftertreatment components.
Installation Notes
Cool the engine and exhaust system before beginning. Remove the existing DPF and inspect adjoining piping, sensors, and seals. Install the new filter, torque fasteners per Cummins specifications, and ensure proper sealing. After installation, clear any error codes and run a regeneration cycle to verify proper functionality.
Final Thoughts
For emission control and system integrity, the correctly matched DPF for your Cummins B6.7 / L9 engine is essential. With optimized design, durability, and proper fitment, this filter helps keep your aftertreatment system operating effectively.
