Y-Bridge Kit 3in. 2006-2007 Duramax LBZ Illusion Purple

This upgraded high-flow intake kit for the 2006-2007 6.6L Duramax diesel engine replaces the OEM upper intake manifold. The OEM Y-bridge is poorly designed, a slip-fit two-piece style with minimal support, and is prone to blowing apart under boost, leading to poor drivability and decreased power in hard-working and high-performance trucks. This kit features a much improved, high-flow, bolt-together style two-piece 3" bridge that provides a secure sealing surface where the air inlet horn connects. The kit includes 3" high-flow upper and lower intercooler pipes with smooth mandrel bends and CNC machined billet flanges, perfectly complementing the Y-bridge to offer a full 3" tract from the intercooler pipe slip connection to the engine, incorporating the factory grid heater and EGR connection controls. It is compatible with the OEM lower passenger side intercooler pipe as well as the upgraded 3.5" High Flow Passenger Side Intercooler Pipe Kit (WCF100367). The product is available in custom powder coat colors and is compatible with stock trucks, requiring no additional modifications, upgrades, or tuning for installation. It pairs best with emissions-compliant tuning and drop-in turbochargers for optimum performance gains.
