Engineered specifically for the updated 2024 Duramax platform, the Banks Ram-Air Oiled Intake System delivers substantially more airflow than the restrictive factory intake while maintaining factory drivability and emissions compliance.

Unlike conventional aftermarket intakes, Banks developed a patented Air Mass Control Module to overcome the tighter airflow monitoring introduced on 2024 L5P models. This allows the intake to achieve up to 58% greater air mass flow than stock without triggering a Check Engine Light, resulting in sharper throttle response, improved turbocharger performance and increased fuel economy.

The system features Banks' oversized Big-Ass Oiled Air Filter, a large two-piece XLPE enclosed airbox, Banks Super-Tube intake and an EPDM silicone bellows coupler that accommodates engine movement while maintaining smooth, unrestricted airflow. The enclosed housing connects directly to the factory hood scoop and forward ram-air ducts while an additional side inlet supplies cool outside air and enhances turbo induction sound.

Purpose-built for the 2024 L5P, this intake is one of the most advanced cold air systems available, providing outstanding airflow, filtration and everyday reliability without requiring ECU tuning.
