The Banks Ram‑Air Intake System for 2017–2019 Chevy and GMC 6.6L L5P Duramax replaces the factory intake with an enclosed housing and an oversized dry filter to increase airflow and reduce soot production. It’s rated to add about +20 hp by itself or up to +81 hp when paired with the L5P Derringer inline tuner. Enclosed design keeps hot engine air out, extends service life, and includes a five‑year limited warranty.
