Wehrli’s Stage 2 4" intake kit for 2017–2019 GM L5P 6.6L Duramax replaces restrictive factory plastic parts with a fabricated aluminum intake pipe and air box to increase airflow to the turbo. The design draws cold air through the hood ram air duct and inner fender for cooler intake temps, better throttle response and improved torque. Removable air box lid, hydrophobic pre‑filter cover, silicone boot and stainless t‑bolt clamps simplify maintenance; bolt‑on, compatible with stock trucks and requires no tuning.
