Intake Horn 5in. for 2006-2010 Duramax LBZ LMM Bengal Silver

The WCFab LBZ/LMM 4.8 inch High Flow Cast Aluminum Intake Horn replaces the restrictive OEM plastic inlet on 2006-2010 Chevrolet and GMC trucks equipped with the 6.6L LBZ/LMM Duramax diesel engine. This upgrade significantly increases airflow to the turbocharger, resulting in improved engine performance and throttle response. The design includes a port for PCV connection and eliminates the factory resonator, which not only enhances the under-hood appearance but also contributes to a more aggressive turbo and engine sound. This intake horn is engineered to complement WCFab Stage 1 LBZ & LMM Intake Kits and is available with a powder-coated finish in a custom color. Requires an aftermarket intake pipe that utilizes a 4-inch silicone boot and clamps for connection.
