Chevrolet Silverado 3500HD Performance Air Intake – Wehrli Y-Bridge Kit – Brizzle Blue – 2006–2007. This upgraded 3 in. two-piece Y-bridge and intercooler piping replaces the factory slip-fit bridge for stronger connections and improved airflow on LBZ Duramax trucks.

Built around WCFab’s bolt-together design, the system provides a full 3 in. tract from intercooler to engine with smooth mandrel bends and CNC-machined billet flanges. It retains the factory grid heater and EGR interfaces, is compatible with the OEM lower passenger-side intercooler pipe or WCFab’s optional 3.5 in. upgrade (WCF100367), and requires no tuning. Finished in Brizzle Blue and Made in the USA, this kit includes all necessary boots, clamps, seals, and hardware, delivering up to a 36% improvement in airflow over stock.
