GMC Sierra Performance Air Intake – Wehrli 5 in Intake Horn, Semi-Gloss Black (2006-2010). Built for LBZ/LMM Duramax VGT applications, this cast-aluminum horn pairs with compatible intake kits to reduce restriction and improve flow to the turbo.

Designed to complement WCFab/Wehrli intakes that use a removable boot with two clamps, this 5 in horn features a 4.8 in inlet, single-stage powder coat, and robust hardware for a secure connection. Not compatible with OEM or aftermarket systems where the intake-to-horn boot is molded to the pipe and not removable. Precision-cast with an O-ring seal and integrated PCV port, it also eliminates the factory resonator junction for a cleaner, higher-flow path.
