GMC Sierra 2500HD Performance Air Intake - Wehrli - 3in Y-Bridge Kit - Kiwi Green - 06-07. A high-flow, bolt-together upgrade for 2006-2007 Duramax LBZ that replaces the failure-prone OEM Y-bridge and improves airflow and reliability.

This Wehrli Custom Fab two-piece 3-inch Y-bridge creates a secure sealing surface at the air inlet horn and provides a continuous 3-inch tract from intercooler pipe to intake runners. Smooth mandrel-bent upper and lower intercooler pipes and CNC machined billet flanges reduce turbulence and reinforce durability. The kit retains factory grid heater and EGR connections, works with stock trucks, and requires no tuning. Includes silicone boot, stainless T-bolt clamps, MAP sensor seal, new O-rings, up-pipe to EGR gasket, and grid heater hardware. Compatible with the OEM lower passenger intercooler pipe and WCFab 3.5-inch passenger side pipe WCF100367.
