Add an additional 20 hp to your 2017-2019 Duramax. Or, combine with the Derringer inline tuner for a total gain of 81 hp. Beats stock and the competition.

New over-sized filter element, largest in its class, protects engine and outflows competition. Enclosed housing keeps out hot, power-robbing engine air. More airflow increases the air-fuel ratio allowing the engine to run more lean, reducing soot output, decreasing the frequency between regens. Dry Air Filter Element.

Banks Ram-Air Superiority: Molded, streamlined filter housing. Lifetime, high-flow Banks Ram-Air filter. Flows more cool, dense ram-air into the engine. Limited Warranty (Filter: Lifetime Limited Warranty).

Banks Ram-Air Versus Stock: The factory air filter housing has little room for air to flow around the filter. The Banks Ram-Air housing has a larger inlet and ballistic-shaped nose, which encourage the reusable air filter to freely inhale for more power.
