The Banks Ram-Air Cold Air Intake System is built for the 2020-2023 Duramax L5P platform with the 6.6L engine. It includes the patented Banks Air Mass Control Module, an electronic device that lets the intake use the Banks SuperTube, an intake tube larger than stock. The system is designed to add power, sharpen turbo response and improve fuel economy.
The enclosed, oversized two-piece XLPE airbox keeps hot engine air away from the filter and increases the volume of cool air around it. It connects to the OEM hood and forward ram air scoops. An extra side inlet opens to the wheel well for fresh air and a stronger induction note. A unique EPDM elbow with bellows allows for engine movement while tapering down to increase air density.
The system is designed to run without a check engine light.
