Chevrolet Duramax LMM Performance Air Intake – Wehrli Intake Horn, 5 in., Flat Black (2006–2010). High-flow turbo inlet horn for LBZ/LMM VGT trucks that replaces the restrictive factory piece.

Built from cast aluminum with a custom single-stage flat black powder coat, this 5 in. horn uses a 4.8 in. inlet to help reduce restriction. It complements WCFab intake kits and includes components for a secure, well-sealed install. Compatibility note: works with intakes that use a removable boot and two clamps; not for systems where the boot is molded to the intake pipe.
