- Patented Air Mass Control Module: This exclusive electronic module is the key to bypassing the Duramax's strict new MAF sensor calibration, ensuring no check engine light while allowing for aggressive performance tuning.
- Unrivaled Size & Capacity: The large, organic shape of the system eliminates restrictions and turbulence, delivering a 58% gain in Mass Air Flow over the stock system.
- Massive "Big Ass Filter": This oiled air filter element is engineered for optimal flow and dirt capacity, giving you more miles between services and flowing freely long after competitors' filters are clogged.
- Maximized Cold Air Density: The system features a durable, heat-resistant Cross-Linked Polyethylene (XLPE) enclosure that seals against power-robbing engine heat. It connects directly to your OEM hood and front ram air scoops, maximizing the ram-air effect at speed.
- Exclusive Bellows-Free Design: A huge, tapering intake elbow made from highly durable EPDM synthetic rubber uses an exclusive bellows design to allow for engine movement while ensuring unobstructed airflow into the turbo, eliminating the drag and turbulence found in factory-style bellows.
- Enhanced Sound: A dedicated side inlet draws fresh air from the wheel well, lowering pressure drop and providing a more audible and aggressive induction note.

You can dramatically enhance the performance and efficiency of your 2024 Duramax 6.6L L5P with the Banks Power Ram-Air Intake System 42285. Your factory intake is an obstacle to power—a restrictive, multi-piece design riddled with bends, corners, and sound resonators that compromise the air path and cause turbulence, ultimately lowering Mass Air Flow. The Banks Ram-Air system is an expertly engineered solution that removes these restrictions and sharpens your turbo response by delivering a massive increase in air mass flow. This system delivers a radical, unrestricted path for the cool, dense air your engine craves, resulting in an unrivaled 58% gain in Mass Air Flow over the stock system. Crucially, because GM's new MAF sensor calibration on the 2024 L5P is so sensitive, traditional performance intakes will trigger a check engine light. Banks engineers have overcome this electronic limitation with a patented Air Mass Control Module, allowing the system to achieve truly unmatched performance gains without compromising your engine's control module (ECM). By maximizing the volume of cool, pressurized, dense air—not just volume—you not only gain horsepower but also achieve impro[...]
