Frequently Asked Questions

Q: Is this turbocharger compatible with non-marine Cummins 5.9L engines? A: While the base engine is similar, marine turbos often have specific cooling or housing configurations. Please verify your existing part number against 3538723 or 3802870 before ordering.

Q: Does this unit require professional installation? A: Professional installation is highly recommended to ensure proper oil priming and to prevent premature failure of the new turbocharger.
