The GMC 3500 HD Performance Air Intake by Wehrli is the ultimate upgrade for truck enthusiasts seeking enhanced efficiency and power for their 2001-2004 Duramax LB7. This high flow intake horn, crafted with precision from top-grade materials, ensures optimized airflow and engine performance, wrapped in a sleek, gloss black finish.

The Wehrli Air Intake is designed to replace the factory-installed turbo mouthpiece, which is often restrictive. By doing so, this product significantly increases the airflow to your turbocharger, resulting in better engine performance and improved throttle response. Compatible with both the stock IHI Turbo and upgraded models, it is a versatile addition to any performance build. Not only does it offer quicker spool-up times, but the performance gains are substantial, with potential horsepower increases ranging from 10-20 HP, depending on your vehicle's tuning and specifications. Made in the USA, this intake horn blends craftsmanship and function seamlessly.
