GMC Sierra 2500HD Performance Air Intake - Wehrli 3in Y-Bridge Kit, Bengal Grey, for 2007.5–2010 Duramax LMM. A robust bolt-together upgrade that replaces the weak OEM slip-fit bridge to improve airflow and reliability under boost.

This high-flow assembly creates a continuous 3 in tract from intercooler to engine with smooth mandrel-bent upper and lower pipes and CNC-machined billet flanges. It retains the factory grid heater, throttle valve, and EGR connections, works with stock trucks, and requires no tuning. Finished in Bengal Grey powder coat and made in the USA, it’s compatible with the OEM lower passenger-side intercooler pipe and WCFab’s 3.5 in passenger-side upgrade.
