WCFab 4" Stage 2 intake kit for 2017–2019 GM Duramax L5P 6.6L replaces restrictive factory plastic parts with a fabricated aluminum 4" intake pipe and airbox to increase airflow to the turbo. The bolt-on system draws cold air through hood ram-air ducts and inner fender paths, lowers intake temperatures, improves throttle response and torque, and includes a dry filter with hydrophobic pre-filter; no tuning required for stock trucks.
