The point of a cold-air intake is simple: get the engine a cleaner, less restricted supply of outside air. The Banks Ram-Air Intake System does that with a freer-flowing intake path, and this setup adds a SuperScoop under the bumper to take advantage of the high-pressure air around the truck at speed. That helps push a colder, denser air charge up into the Duramax instead of relying on hotter underhood air. We also built splash control into the filter mount, so the system is better protected when the truck sees rough off-road use. Less restriction, better outside-air supply, and smarter real-world packaging all work toward the same goal—better breathing where the truck actually runs.
The video opens by framing a cold air intake system as an essential upgrade for improving performance on a late-model vehicle. In this case, the focus is the Banks Ram-Air intake package, presented as a system designed to improve the engine's breathing by delivering a greater volume of cooler, denser air.
According to Banks, the Ram-Air portion of the package provides 42 percent more airflow. The stated goal is to let the engine breathe more freely, which is especially important on a Duramax application where intake restriction can limit performance. The recap emphasizes that this added airflow is not just a cosmetic change but a measurable increase intended to support a higher-performance setup.
The intake's filter mounting arrangement includes a flat section that serves a secondary protective purpose. That flat spot acts as a splash guard during hard off-road use, helping shield the filter area when the vehicle is exposed to water and debris. The design is presented as a practical detail that supports durability and consistent intake performance in harsher driving conditions.
Banks extends the system beyond a conventional underhood intake by adding a functional Ram-Air component mounted beneath the bumper. This placement is intended to capture airflow from outside the engine bay rather than relying solely on underhood air. By positioning the inlet in this area, the system can take advantage of the airflow pattern around the moving vehicle.
A key engineering point in the segment is that the Ram-Air assembly uses the air envelope surrounding the vehicle at speed. As the truck moves, this airflow is directed into the intake path, helping feed the engine with a colder and denser air charge. The explanation ties the system's effectiveness to vehicle motion, where the external airflow can be used to improve the quality and quantity of incoming air.
The intended result is to push that colder, denser intake charge up into the Duramax. The recap presents the Banks Ram-Air system as a complete intake solution that combines increased airflow, off-road-minded filter protection, and a bumper-mounted fresh-air source. Together, those elements are described as supporting better engine breathing and making the intake upgrade more functional than a basic replacement system.
