GMC Duramax Performance Air Intake – Wehrli 3in Y-Bridge Kit, Cat Yellow (2006–2007 LBZ). A high-flow, bolt-on replacement for the failure-prone OEM Y-bridge.

Designed for the LBZ, the two-piece, bolt-together 3" Y-bridge delivers a rigid, leak-resistant connection at the air inlet horn. Matching 3" upper and lower intercooler pipes use smooth mandrel bends and CNC-machined billet flanges to reduce restriction. It retains the factory grid heater and EGR connections, requires no tuning, and comes with silicone boot, stainless T-bolt clamps, MAP seal, O-rings, gaskets, and hardware. Compatible with the OEM lower passenger-side intercooler pipe.
