Chevrolet Silverado Performance Air Intake – Wehrli Y-Bridge Kit – Bengal Silver (2006–2007 LBZ). Replace the restrictive factory upper intake on your LBZ Duramax with WCFab’s 3-inch, two-piece Y-bridge and matching intercooler piping for confident fitment and improved airflow.

The OEM slip-fit Y-bridge is known to separate under boost, causing drivability issues and power loss. This bolt-together 3-inch bridge provides a secure sealing surface at the air inlet horn and mates to 3-inch upper and lower intercooler pipes for a consistent, high-flow tract. Smooth mandrel bends and CNC-machined billet flanges help reduce turbulence, while factory grid heater and EGR connections are retained. Finished in Bengal Silver powder coat, this kit installs on stock trucks with no tuning required and includes premium silicone, clamps, seals, and hardware. Made in the USA.
