Patented Ram-Air Intake for 2020-22 Duramax

In our latest explainer video, Arlen details the brand new patented Ram-Air intake for the 2020-22 Duramax. With 2020 and newer 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.

You’ll see in the video that the stock intake is made up of three pieces. Each of them adds resistance and drag to the intake, and they are only here for noise reduction.

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 Duramax L5P 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. An extra side inlet opens up to the wheel well for fresh air and owners will enjoy stronger induction sound. Patented Ram-Air Intake – US Patent #11,193,441
