Cummins B6.7, L9 DPF 2018-2022

Emission Protection Upgrade: Cummins B6.7 / L9 DPF (2018–2022)

What is it?
The Cummins B6.7 / L9 DPF (Diesel Particulate Filter) for 2018–2022 engines is a crucial part of the exhaust aftertreatment system. It traps soot and particulate matter from engine exhaust, helping reduce emissions and protect downstream emissions components.

Why choose this DPF?
This DPF is specifically engineered for B6.7 / L9 engines in the 2018–2022 model range. Using a properly matched unit helps avoid issues like excessive backpressure, frequent regenerations, or emissions errors that come from incompatible or low-quality replacements.

Key Benefits
✅ Designed for Cummins B6.7 and L9 engines (2018–2022)
✅ Efficiently captures soot and harmful particulates
✅ Helps prevent engine derating and error codes
✅ Built to endure high heat and harsh exhaust conditions
✅ Direct-fit design allows easier installation

Applications
Suitable for medium-duty trucks, buses, and industrial machines powered by Cummins B6.7 or L9 engines from 2018–2022. It supports reliable emissions performance wherever a robust aftertreatment system is needed.

Installation Notes
Allow the engine and exhaust to cool fully before installation. Remove the old DPF and inspect the piping, sensors, and connecting gaskets. Fit the new DPF, torque all hardware to Cummins specifications, and ensure all seals are secure. After installation, clear fault codes (if any) and run a regeneration cycle to validate proper operation.

Final Thoughts
To maintain emissions integrity and system reliability, your Cummins B6.7 / L9 engine deserves the right DPF. With matched construction, durability, and correct fit, this component keeps your emissions system functional and compliant.
