The Wehrli Custom Fab 4" intake kit for 2017–2019 GM Duramax L5P 6.6L replaces restrictive factory plastic parts with an aluminum 4" intake pipe and air box to improve airflow to the turbo. It uses aerodynamic bends, a dry filter with hydrophobic pre-filter cover, stainless t-bolt clamps and silicone boots, draws cold air through factory ram air ducts, bolts on to stock trucks with no tuning required, and is finished in custom powder coat colors.
