Product Description

The Banks 42249-D Ram-Air Cold-Air Intake System with Dry Filter is a performance-enhancing replacement for the restrictive stock intake on 2017-2019 Chevrolet Silverado and GMC Sierra 2500/3500 HD trucks equipped with the 6.6L Duramax L5P diesel engine. Featuring a streamlined molded intake housing and a large dry reusable air filter element, this system boosts airflow to the engine by minimizing restrictions found in the factory setup, helping your Duramax breathe more efficiently and run cooler.

By improving airflow and increasing air density, the Banks Ram-Air intake can help raise power and torque potential - often adding around +20 hp on stock trucks - and also helps lower soot output and reduce the frequency of diesel particulate filter (DPF) regenerations. The enclosed housing design keeps hot engine air out, while the oversized dry filter element is easy to maintain and engineered for long service life. This intake system is 50-state emissions compliant under CARB EO D-161-118 and comes with a 5-year limited warranty, offering a durable, direct-fit upgrade for your L5P Duramax.
