The Banks Ram‑Air Intake for 2017–2019 Chevy/GMC 6.6L Duramax (L5P) replaces the factory intake with an enclosed system and the largest over‑sized oiled filter in its class to deliver more airflow. By itself it adds about +20 hp and reduces soot output and regen frequency; combined with Banks’ Derringer inline tuner reported gains reach a total of +81 hp. The design helps the engine run cooler and extends service intervals.
