Chevrolet Silverado Performance Air Intake - Wehrli - Stage 2, 4in - WCFab Grey - `20-`24 is a high-flow replacement intake for 2020-2024 L5P 6.6L Duramax Chevrolet Silverado / GMC Sierra 2500/3500 HD trucks. It replaces restrictive factory plastic components with a fabricated aluminum 4-inch intake and dry filter assembly to improve airflow to the turbo.

This Stage 2 Wehrli kit features all-aluminum construction with large-diameter 4-inch piping, smooth aerodynamic bends, and an intake horn over an inch larger than OEM to reduce restriction immediately before the turbo inlet. The design draws cold air through the hood Ram Air duct and inner fender to help lower intake temperatures and sharpen throttle response without making unverified performance claims. The kit includes a 10G aluminum air box and lid, high-quality silicone boot, stainless steel T-bolt clamps, Outerwears pre-filter cover and a dry filter element. It is a bolt-on solution for stock trucks with no tuning required. Important: failure to disable the air filter monitor system will trigger a service air filter message and may require a dealership reset.
