The new Banks Ram-Air intake system for the 2020-22 Duramax 6.6L is now available for pre-order! The innovative cold air intake adds power, sharpens turbo response, and improves fuel economy.
The greater the air mass, the easier it is for your engine to make the same horsepower while using less fuel. In other words, fuel economy! Yes, airflow (CFM) is important, but if the system flows more air, and that air is hot, you’ll likely see a loss in horsepower. Pressurized, cool, dense air is the winning combination. To learn more about air density, see this article.
The ECM (engine control module) in your 2020-22 Duramax monitors air mass and pressure so closely that any deviation from stock results in a check engine light. This means that competitive aftermarket intakes must flow the same as stock. The new patented Banks Air Mass Control Module allows our engineers to design past this electronic limitation. In other words, we are not limited by stock airflow constraints. U.S. Patent #11,193,441
