The Wehrli 4" intake kit for 2017–2019 Chevrolet Duramax L5P swaps restrictive factory parts for a fabricated aluminum 4" intake pipe and sealed air box with dry filter and pre-filter cover. It draws cold air through the hood ram air duct and inner fender to lower intake temps while increasing airflow to the turbo for improved horsepower, torque and throttle response. Includes ram air seal relocated to the hood bottom, silicone boot, stainless t-bolt clamps and removable lid for service.
