What is it?
The Cummins B6.7 turbo assembly, identified by OEM 6395688, is a turbocharger system designed for Cummins B6.7 diesel engines produced 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 engine performance. 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 are essential for maintaining proper airflow 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. Over time, turbochargers can experience wear from high exhaust temperatures, soot accumulation, and bearing fatigue, potentially causing reduced boost pressure, slower throttle response, or excessive exhaust smoke. Replacing the unit with the correct OEM-matched turbo assembly helps maintain stable airflow and consistent engine operation.
