GMC Sierra 2500HD Performance Air Intake - Wehrli 3in Y-Bridge Kit, Candy Teal (2007.5–2010). A high-flow, bolt-on upgrade that replaces the restrictive OEM upper intake on LMM Duramax trucks.

Built around WCFab’s two-piece, bolt-together 3-inch Y-bridge, this kit pairs 3-inch upper and lower intercooler pipes with smooth mandrel bends and CNC-machined billet flanges to improve airflow and durability. It addresses the slip-fit factory joint known to separate under boost, providing a secure sealing surface for the air inlet horn. The assembly retains the factory grid heater, throttle valve, and EGR connections, works with the OEM passenger-side lower intercooler pipe or WCFab’s 3.5-inch upgrade, and requires no tuning.
