The WCFab 4‑inch intake kit for 2017–2019 GM 6.6L L5P Duramax replaces restrictive factory plastic with a fabricated aluminum intake pipe and air box to increase airflow to the turbo, improving throttle response, intake temperatures, and induction sound. It draws cold air through the hood ram‑air duct, includes a dry filter with a hydrophobic pre‑filter cover, silicone boot, stainless t‑bolt clamps, and installs as a bolt‑on with no tuning required.
