Introducing the GMC Sierra 3500 HD Performance Air Intake by Wehrli, Stage 2, 4-inch with a Semi-Gloss Black finish designed for the 2020-2024 models. This advanced air intake system is engineered to replace the restrictive factory components on the 6.6L Duramax L5P engine, elevating the performance of your vehicle to new heights while maintaining reliability.

This system boasts a high-flow, fabricated aluminum intake pipe and air box enclosure paired with a high-quality dry filter assembly. By directly increasing airflow to the turbo, it enhances horsepower, torque, and throttle response. Its design promotes cooler intake temperatures by efficiently channeling cold air through the innovative hood Ram Air duct and inner fender. The smooth bends and large diameter piping enhance intake air velocity and volume, delivering a distinctive and aggressive engine note during acceleration. The intake horn, over an inch larger than its OEM counterpart, eliminates airflow restrictions just before the turbo inlet.
