Ram-Air Intake System Dry Filter for 2017-2019 Chevy/GMC 2500/3500 6.6L Duramax, L5P 42249-D

Add an additional +20 hp to your 2017+ 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.

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.

*Tests were performed on the same flow bench under the same conditions, with the MAF sensor installed.
