This LBZ 3" Y-Bridge Kit is an upgraded high flow intake kit for the 2006-2007 LBZ Duramax which replaces the OEM upper intake manifold supplying air to the engine intake runners. The OEM Y-bridge for these trucks is a poorly designed, slip-fit style two piece bridge with very little support and is prone to blowing apart under boost on hard working and high performance trucks creating poor drivability and decreased power. This kit is a much improved, high flow, bolt together style two piece 3" bridge which provides a secure sealing surface where the air inlet horn connects to the bridge. 3" high flow upper and lower intercooler pipes feature smooth flowing mandrel bends, CNC machined billet flanges and perfectly compliment the y-bridge to offer a full 3" tract from intercooler pipe slip connection to the engine incorporating the factory grid heater and EGR connection controls. Compatible with OEM lower passenger side intercooler pipe as well as our upgraded 3.5" High Flow Passenger Side Intercooler Pipe Kit WCF100367. Finished in your choice of custom powder colors. This product is compatible with stock trucks requiring no additional modifications, upgrades, or tuning for installation. Pairs best with emissions compliant tuning and drop in turbochargers for optimum performance gains.
