Y-Bridge Kit 3in. 2007.5-2010 Duramax LMM Grape Frost

This LMM 3" Y-Bridge Kit is an upgraded high flow intake kit for the 2007.5-2010 LMM Duramax. It replaces the OEM upper intake manifold, which is prone to blowing apart under boost due to its poorly designed, slip-fit style two-piece construction. The Wehrli kit features a much improved, high-flow, bolt-together style two-piece 3" bridge, providing a secure sealing surface where the air inlet horn connects to the bridge. The kit also includes 3" high flow upper and lower intercooler pipes with smooth flowing mandrel bends and CNC machined billet flanges, complimenting the y-bridge to offer a full 3" tract from the intercooler pipe slip connection to the engine, incorporating the factory grid heater, throttle valve, and EGR connection controls. It is compatible with the OEM lower passenger side intercooler pipe as well as Wehrli's upgraded 3.5" High Flow Passenger Side Intercooler Pipe Kit (WCF100367). This product is compatible with stock trucks and does not require additional modifications, upgrades, or tuning for installation. It pairs best with emissions-compliant tuning and drop-in turbochargers for optimum performance gains.
