GMC Sierra Performance Air Intake - Wehrli - Stage 2, 4in - WCFab Grey - `20-`24. A bolt-on, high-flow intake kit designed for 2020-2024 L5P 6.6L Duramax trucks that replaces restrictive factory plastic components with a fabricated aluminum air box and 4" piping for improved airflow and response.

This Wehrli Stage 2 system uses all-aluminum construction with smooth, aerodynamic bends and a larger intake horn to reduce restriction just before the turbo inlet. It draws cooler air through the hood Ram Air duct and inner fender, increasing intake volume and velocity for more responsive throttle feel, improved engine and turbo sound during acceleration, and cooler intake temperatures. Finished in WCFab Grey powder coat, the kit includes a dry filter assembly, silicone boot, stainless T-bolt clamps, and seals to mate to the functional Ram Air port. No additional tuning is required for stock trucks. Note: failure to disable the air filter monitor system will produce a service message and may require dealer reset.
