Banks Cold Air Intake



Fits 2020-2023 Duramax


A groundbreaking cold air intake featuring the patented Banks Air Mass Control Module. The electronic device allows our engineers to design past stock size and airflow limitations, putting the Ram-Air system in a league of its own. No other intake even comes close. Adds power, sharpens turbo response, and improves fuel economy. Beats stock and competitors where it matters most; mass airflow, pressure retention, and dirt capacity. Provides a strong induction note.

Brand new for the 2020-2023 L5P platform, the Banks Ram-Air intake is a game-changer. With 2020 and up Duramax engines, GM has further tightened the allowable range for induction tuning. To counter this, Banks engineers have designed a new patented Air Mass Control Module that allows an intake design to go beyond these limitations for truly unmatched airflow performance.

With a Big-Ass filter, huge induction tube and a unique bellowed silicone coupler to allow for engine movement while tapering down to increase air density, your 6.6L engine will breathe easy and cleanly. Its enclosed airbox design keeps power-robbing heat away and attaches to the OEM hood and front ram air scoops for even better performance at speed on the highway. An extra side inlet opens up to the wheel well for fresh air and a strong induction note sound.
