The Chevrolet Duramax Performance Air Intake by Wehrli, featuring a High Flow Cast Aluminum Horn in WCFab Grey, is designed for the 2011-2016 models. This high-quality intake system replaces the restrictive OEM plastic inlet, enhancing airflow, and improving both throttle response and engine performance.

Crafted with precision, this intake horn is tailor-made to fit the Duramax LML engines, ensuring optimum compatibility and performance. The cast aluminum construction guarantees durability and resilience under high-performance conditions. Furthermore, this product includes a dedicated port for PCV connection, effectively eliminating the resonator for a more aggressive turbo and engine sound. The Wehrli air intake horn is designed to complement the WCFab Stage 1 LML Intake Kits and Stage 1 High Flow Bundle Kits, and is not compatible with OEM and aftermarket intakes that do not use a silicone boot connection at the horn.
