The WCFab Stage 2 4" intake kit for 2017–2019 GM L5P 6.6L Duramax replaces the factory plastic intake with a high-flow fabricated aluminum pipe and air box to improve airflow to the turbo. The system draws cold air via the hood ram-air duct, uses large-diameter smooth bends, stainless clamps, silicone boots and a dry filter with a hydrophobic pre-filter cover. It’s a bolt-on upgrade compatible with stock trucks.
