The Ram-Air intake system for the 2025-26 Duramax 6.6L widens the powerband, sharpens turbo response, and improves fuel economy by improving air mass flow to the turbo. This is made possible by our patented Banks Air Mass Control Module and Crankcase Ventilation Control Modules. Meanwhile, all competitors must retain near stock airflow or risk setting a check engine light.
