The GMC Sierra 2500HD Intake Horn by Wehrli is a high-quality performance component designed for the 2011-2016 Duramax LML models. This high-flow cast aluminum intake horn, featuring an eye-catching Bengal Red finish, is engineered to enhance airflow to your turbo, offering improved performance and throttle response.

Crafted from durable cast aluminum, the Wehrli Intake Horn not only replaces the restrictive OEM plastic inlet but also eliminates the resonator for a more robust turbo and engine sound. It is specifically designed to integrate seamlessly with the Stage 1 LML Intake Kits and Stage 1 High Flow Bundle Kits. Additionally, this intake horn comes with a port for PCV connection, O-ring seal, new EGR gaskets, and is custom powder-coated for long-lasting aesthetics and performance. Note that it is a perfect fit for intake pipes compatible with a 4" boot and clamp connection only.
