GMC Sierra 2500HD Performance Air Intake - Wehrli Y-Bridge Kit, 3in., High Flow, Bronze Chrome (2006-2007) for LBZ Duramax. Upgrades the OEM upper manifold with a robust, bolt-together design.

The stock slip-fit Y-bridge can separate under boost; Wehrli’s 3 in. two-piece bridge seals securely at the air inlet horn. Matching 3 in. upper crossover and lower intercooler pipes use mandrel bends and CNC-machined flanges to reduce restriction. It retains the factory grid heater and EGR connection controls, fits stock trucks, and needs no tuning. Bronze Chrome finish; compatible with the OEM lower passenger-side intercooler pipe or WCFab’s 3.5 in. upgrade (WCF100367). 36% airflow gain over stock.
