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.
