The GMC 3500 HD Performance Air Intake by Wehrli is an impressive upgrade for your `01-`04 Chevrolet Silverado or GMC truck. This High Flow Intake Horn, finished in striking Candy Red, is designed specifically for the 6.6L Duramax Diesel, ensuring optimal airflow to elevate your vehicle's performance.

This allows for significant increases in airflow, resulting in improved engine performance and throttle response. Whether you're using the factory IHI Turbo or upgraded versions, this high-flow intake horn is guaranteed to enhance your truck's capabilities, especially in max-effort tuned setups or when paired with custom performance enhancements.
