Wehrli 20-24 Chevrolet L5P Duramax 4in Intake Kit - PMB-10902 (Whiskey Bronze)

This 4-inch performance air intake system with an air box by Wehrli is designed for 2020-2025 Chevrolet Silverado 2500/3500 and GMC Sierra 2500/3500 trucks equipped with the 6.6L L5P Duramax engine. It features a fabricated aluminum intake pipe and air box enclosure with 4-inch piping and aerodynamic bends. This system replaces restrictive factory plastic components, enhancing airflow to the turbo, which improves horsepower, torque, and throttle response while maintaining low intake temperatures. Cold air is drawn through the hood's Ram Air duct and inner fender. The durable aluminum construction and custom powder coat finish contribute to improved air velocity and a more robust engine and turbo sound. It's a simple bolt-on installation requiring no tuning.
