The GMC 3500 HD Performance Air Intake by Wehrli is designed specifically for the 2001-2004 Duramax LB7 engine models, finished in a striking Bengal Silver. This high-performance air intake system is crafted to enhance airflow to your turbocharger, improving combustion efficiency and engine response.

Replacing the restrictive OEM turbo mouthpiece, this high-flow cast aluminum turbo intake horn maximizes airflow, yielding impressive gains of up to 15-20 HP, especially noticeable in max-effort tuned vehicles or those with upgraded turbochargers. Precision CNC machining ensures a perfect fit with both the factory IHI Turbo and aftermarket options. The custom powder-coated finish not only provides a sleek look but adds durability. The installation is straightforward with no tuning required, and it includes all necessary mounting hardware for a hassle-free upgrade.
