Chevrolet Silverado 2500HD Performance Air Intake – Wehrli 3in Y-Bridge Kit, Kiwi Green (06–07). High-flow upgrade for 2006–2007 Duramax LBZ, replacing the weak OEM Y-bridge with a robust 3-inch bolt-together design.

Built to correct the slip-fit factory joint that can separate under boost, this WCFab system delivers a secure seal and smoother airflow. The two-piece 3-inch Y-bridge pairs with 3-inch upper crossover and lower intercooler pipes, all mandrel-bent with CNC billet flanges. Retains grid heater and EGR, installs on stock trucks with no tuning, and remains compatible with the OEM lower passenger-side pipe.

Features

• Signature 3-inch bolt-together two-piece Y-bridge
• Up to 36% airflow improvement over stock
• 3-inch upper crossover and lower intercooler pipes
• CNC billet flanges and smooth mandrel bends
