A groundbreaking cold air intake featuring the patented Banks Air Mass Control Module. The electronic device allows our engineers to use the Banks SuperTube, a massive free-flowing intake tube, larger than stock and all competitors.No other cold air intake even comes close in size or airflow. Adds power, sharpens turbo response, and improves fuel economy. Beats stock and competitors in mass airflow, pressure retention, and dirt capacity. Provides a strong induction note.Brand new for the 2020-2023 Duramax 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.Key Features: Includes brand new Patented Banks Air Mass Control Module. "Big Ass Filter" Extends service life and requires fewer cleanings. Enclosed housing keeps out hot, power-robbing engine air. Unique EPDM elbow with exclusive bellows for engine movement. Oversized airbox increases cool air volume around filter. Massive two piece XLPE airbox for easy servicing. Connects to OEM hood and forward ram air scoops. More audible and aggressive induction note. Oiled Air Filter Element. 5-year Limited Warranty. No Check Engine Light. US Patent #11,193,441
- Adds power, sharpens turbo response, and improves fuel economy. 58% air mass flow gain over stock.
