The GMC 2500 HD Performance Air Intake by Wehrli is a high-quality, precision-engineered component designed to enhance the performance of your 2001-2004 GMC or Chevrolet Silverado 2500/3500 HD equipped with the 6.6L Duramax Diesel engine. Finished in a striking Cat Yellow, this 4-inch high-flow cast intake is crafted to deliver superior airflow dynamics for your vehicle’s turbocharger.

Designed to replace the restrictive OEM turbo mouthpiece, the Wehrli air intake significantly improves airflow efficiency, resulting in enhanced engine performance and throttle responsiveness. This component is compatible with factory IHI Turbos, upgraded drop-in IHI Turbos, and various aftermarket intakes. For trucks with max-effort tuning, potential power gains range from 10-15 HP, while those with upgraded turbochargers can see up to 20 HP improvements. Notably, this intake features a custom powder-coated finish and is proudly manufactured in the USA.
