The GMC 3500 HD Performance Air Intake by Wehrli, featuring the High Flow Cast Aluminum Turbo Intake Horn in WCFab Red, is a must-have for enthusiasts looking to optimize their `17-`24 model trucks. Designed explicitly for 6.6L Duramax Diesel engines, this component replaces the restrictive OEM plastic turbo mouthpiece with a highly efficient aftermarket solution.

With its robust all-aluminum construction, the intake provides increased durability and enhances engine sound for a more aggressive auditory experience. Thanks to its larger, smooth-flowing design that integrates an anti-surge face, the intake offers significantly better airflow into your turbocharger, optimizing engine performance and throttle response without needing additional tuning. It’s engineered to work seamlessly with stock trucks and is compatible with both OEM and aftermarket drop-in turbochargers, making it a versatile addition to your vehicle. For those looking to maximize performance, pair it with our Stage 1 L5P Cold Air Intake Kits and High Flow Bundle Kits for a comprehensive upgrade.
