Chevrolet Silverado 3500HD Performance Air Intake - Wehrli Y-Bridge Kit, 3 in., High Flow, Bronze Chrome, '06-'07. Built for the 2006-2007 Duramax LBZ, this two-piece upgrade replaces the weak factory upper intake with a stronger, higher-flow bridge and piping.

WCFab’s bolt-together 3 in. Y-bridge replaces the slip-fit OEM joint that can split under boost, improving reliability and airflow. Smooth 3 in. mandrel-bent upper/lower intercooler pipes and CNC billet flanges maintain a consistent 3 in. path to the runners while retaining factory grid heater and EGR provisions. Compatible with the OEM passenger-side lower pipe or WCFab’s 3.5 in. upgrade (WCF100367). Bronze Chrome finish. No tuning required. Includes silicone boot, stainless T-bolt clamps, MAP seal, O-rings, EGR gasket, and grid-heater hardware.
