The Wehrli Custom Fab 4" intake kit replaces restrictive plastic factory parts on 2020–2024 Chevrolet and GMC trucks with the L5P 6.6L Duramax, using a fabricated aluminum 4" intake pipe and sealed airbox to increase airflow to the turbo. It draws cold air through the hood ram-air duct and inner fender for improved throttle response and cooler intake temps. Constructed from 10-gauge aluminum with a dry filter and powder-coat finish, the bolt-on kit requires no tuning and fits stock trucks without other modifications.
