GMC Sierra 2500HD Performance Air Intake - Wehrli - 3in Y-Bridge Kit - Candy Teal - 06-07. Built for 2006-2007 Duramax LBZ trucks, this high-flow, bolt-together upgrade replaces the weak OEM Y-bridge for stronger, more consistent intake performance.

WCFab’s two-piece 3 in bridge pairs with matching 3 in intercooler pipes to provide a continuous 3 in path from the intercooler to the engine. Smooth mandrel bends and CNC-machined billet flanges promote airflow and reliable sealing, while provisions retain the factory grid heater and EGR control. It is compatible with stock trucks, requires no tuning, and comes finished in Candy Teal powder coat.
