The WCFab 4" Intake Kit from Wehrli is a complete aluminum intake and air box assembly for 2017–2019 GM L5P 6.6L Duramax trucks that replaces restrictive factory plastic parts to increase airflow to the turbo. It draws cold air via the hood ram air duct and inner fender, improving horsepower, torque, throttle response and intake temperatures. Durable silicone boots, stainless t-bolt clamps, a dry filter with hydrophobic pre-filter cover, and a removable lid make maintenance straightforward while preserving a clean engine bay and offering custom powdercoat finishes.
