Wehrli Custom Fab Stage 2 4" intake kit for 2020–2025 Chevrolet/GMC Duramax L5P 6.6L installs as a high-flow aluminum intake and airbox with dry filter to replace restrictive factory parts. Designed to draw cold air through the hood ram air duct and inner fender, the kit uses 4" piping and a larger intake horn to improve airflow to the turbo for stronger throttle response, cooler intake temperatures and a more aggressive induction sound. Bolt-on with no tuning required.
