The Wehrli 4" intake kit for 2017–2019 Duramax L5P 6.6L in flat black replaces the factory plastic intake with a fabricated aluminum 4" pipe and sealed air box with dry filter. Designed to draw cooler air through the hood ram duct and inner fender, it improves airflow, throttle response, and intake temps without requiring tuning. The kit includes silicone boots, stainless t-bolt clamps, a pre-filter cover, and ships as a bolt-on upgrade compatible with stock trucks.
