Chevrolet Silverado 2500HD Performance Air Intake – Wehrli Y-Bridge Kit, 3in., Flat Black (2007.5–2010). This high-flow upgrade replaces the restrictive factory upper intake to deliver stronger, more reliable charge-air routing on LMM Duramax trucks.

Engineered as a robust, bolt-together two-piece bridge, this WCFab kit addresses the OEM slip-fit design that can separate under boost. Matched 3 in. upper and lower intercooler pipes use smooth mandrel bends and CNC-machined billet flanges to create a consistent 3 in. tract from intercooler to engine while retaining the factory grid heater, throttle valve, and EGR connections. Compatible with stock trucks—no tuning required—and works with the OEM lower passenger-side pipe or WCF100367 3.5 in. upgrade. Finished in flat black powder coat. Made in the USA.
