The GMC Sierra 3500 HD Performance Air Intake by Wehrli is a premier upgrade for your 2020 to 2025 L5P 6.6L Duramax engine trucks. This 4-inch Intake Kit is designed for high flow, improving your truck's performance with a sleek gloss white finish that complements the rugged look of your GMC Sierra.

This Wehrli Performance Air Intake system transforms your GMC Sierra by replacing the restrictive plastic factory parts with a robust aluminum intake pipe and air box enclosure. By increasing airflow to the turbo, this system enhances engine horsepower and torque, delivers quicker throttle response, and reduces intake temperatures. The 4-inch piping with smooth aerodynamic bends ensures higher intake air velocity and volume, leading to a more aggressive engine and turbo sound. Constructed entirely from aluminum, the kit is finished with WCFab's signature custom powder coat colors. The installation is made convenient with basic hand tools, requiring no tuning and fitting seamlessly with stock trucks without any additional modifications.
