Chevrolet Silverado 3500HD Performance Air Intake - Wehrli - Stage 2 - Deore Gold - '17-'19. A bolt-on intake kit designed for the 6.6L L5P Duramax, offering a high-flow aluminum pipe and air box to replace the restrictive factory components.

This Wehrli Stage 2 kit focuses on improved airflow and durability for stock trucks. The kit uses large-diameter 4" piping with smooth bends, a 3.5" intake horn, and a fabricated aluminum air box with a removable lid for easy inspection. It draws cold air through the hood ram air duct and inner fender, uses a dry filter with an Outerwears hydrophobic pre-filter cover, and includes high-quality silicone boots, seals, and stainless steel t-bolt clamps for reliable fitment. No tuning is required for installation; the kit is finished in Deore Gold two-stage powder coat for corrosion resistance and visual distinction.
