The WCFab 4" intake kit for 2017–2019 GM L5P 6.6L Duramax replaces the restrictive factory plastic parts with a fabricated aluminum 4" intake and air box enclosure. Designed to draw colder air through the hood ram-air duct, it increases intake volume and velocity, improves throttle response and intake temperatures, and includes a dry air filter with pre-filter cover. The kit is supplied to bolt on without tuning and fits stock trucks without other upgrades.
