What is it?
The Cummins B6.7 turbo assembly, identified by OEM 6395645, is a turbocharger system designed for Cummins B6.7 diesel engines manufactured between 2022 and 2024. This assembly uses exhaust gas energy to generate boost pressure, increasing airflow into the engine to support efficient combustion and dependable operation. It is engineered specifically for EPA21 B6.7 applications and integrates with factory-installed intake, exhaust, and emissions systems.
Why choose this Turbo Assembly?
Turbochargers play an important role in maintaining airflow balance and combustion efficiency in modern diesel engines. This turbo assembly is manufactured to match Cummins B6.7 specifications, ensuring compatibility with factory sensors, actuators, and aftertreatment components.
