Wehrli WCFab Intake Horn for 2011–2016 6.6L Duramax LML applications is a cast-aluminum high-flow inlet that replaces the restrictive OEM plastic horn to increase airflow to the turbo for crisper throttle response. It features a large 4.8–5.0 inch inlet, a PCV port, silicone reducer, stainless T-bolt clamps and a custom powder-coat finish. The design removes the resonator for a more aggressive induction sound and fits Wehrli Stage 1 LML intake kits while replacing GM inlet part numbers 12642296 and 12637801.
