GMC Sierra 3500HD Performance Air Intake - Wehrli - WCF Y-Bridge Kit - Gun Metal - 07-10. This 3 in high-flow, bolt-together Y-bridge and intercooler piping replaces the weak OEM slip-fit upper intake on 2007.5–2010 Duramax LMM trucks for improved airflow and durability.

Designed as a continuous 3 in tract from the intercooler outlet to the intake runners, the Wehrli two-piece bridge uses smooth mandrel bends and CNC machined billet flanges for a precise, secure fit. It integrates the factory grid heater, throttle valve, and EGR connections, and is finished in Gun Metal powder coat. Compatible with stock trucks, no tuning required, and tested to offer up to 36% improvement in airflow over stock.
