It draws cold air from the hood Ram Air duct and inner fender to boost airflow to the turbo, quicken throttle response, lower intake temps, and add a deeper engine/turbo note under load. Smooth bends, stainless T-bolt clamps, and a silicone boot support a simple bolt-on install. Illusion Blueberry finish. Fits 2020-2025 L5P Sierra/Silverado 2500/3500 HD.
