The GMC 3500 HD Performance Air Intake by Wehrli is a high-flow intake horn, specifically designed for 2001-2004 GMC and Chevrolet Silverado 2500 / 3500 HD trucks equipped with the powerful 6.6L Duramax Diesel engine. Finished in an eye-catching Sparkle Copper, this product offers a superior alternative to the standard OEM turbo mouthpiece, engineered to enhance performance and throttle response.

This high-performance air intake maximizes airflow to your turbocharger, delivering improved engine performance. Made from precision CNC machined cast aluminum, it provides a 40% better flow than the stock part. The upgraded design ensures a smooth transition to the turbo compressor cover, optimizing overall airflow and drivability. Compatible with both factory IHI and aftermarket turbochargers, as well as performance aftermarket intake systems using a 4" boot connection, this intake horn offers a bolt-on upgrade with no tuning required, making it a versatile enhancement for your truck.
