The GMC Sierra 3500 HD Performance Air Intake by Wehrli is a must-have upgrade for your 2001-2004 truck. This high-flow intake horn, finished in an eye-catching Illusion Purple, is designed to enhance the airflow to your turbocharger, ensuring improved engine performance and throttle response.

Constructed from precision CNC machined cast aluminum, this 4-inch inlet turbo intake offers superior airflow, 40% better than the restrictive OEM turbo mouthpiece. This leads to faster spool-up times, potentially yielding 10-15 HP gains for max-effort tuned trucks, and up to 20 HP improvements on vehicles with upgraded turbochargers. The intake horn is compatible with factory IHI Turbo or upgraded drop-in IHI Turbos as well as aftermarket intakes. It ensures optimized airflow and drivability, all while retaining stock compatibility without requiring additional modifications.
