Chevrolet Silverado 3500HD Performance Air Intake – Wehrli WCF Y-Bridge Kit – Gun Metal – 2007.5–2010. A 3-inch high-flow, bolt-together Y-bridge and intercooler pipe upgrade for the LMM Duramax.

Replacing the weak OEM slip-fit bridge, WCFab adds a secure horn-to-bridge seal and a true 3-inch path to the runners. Mandrel bends and CNC billet flanges cut restriction, while factory grid heater, throttle valve, and EGR are retained. It bolts to stock trucks with no tuning and wears a durable Gun Metal powder coat. Testing shows up to 36% more airflow than stock.
