Chevrolet Duramax Performance Air Intake - Wehrli - 3in Y-Bridge Kit - Sparkle Copper - 06-07. This high-flow, bolt-together upgrade for the 2006–2007 LBZ replaces the weak factory Y-bridge and upper intake junction.

Engineered to remove restriction and address slip-fit failures, WCFab’s two-piece 3 in. Y-bridge pairs with 3 in. upper and lower intercooler pipes featuring smooth mandrel bends and CNC-machined billet flanges. The system provides a consistent 3 in. tract from the intercooler connection to the engine while retaining factory grid heater and EGR provisions. It’s compatible with the OEM passenger-side lower intercooler pipe and WCFab’s 3.5 in. upgrade (WCF100367). Finished in Sparkle Copper, this kit installs on stock trucks with no tuning required.
