The only High Flow 3" Complete Y-Bridge kit on the market for your LB7 that is compatible with the factory IHI turbo and aftermarket drop in IHI style chargers! Replace the restrictive OEM Y-bridge and cold side intercooler pipe with this high flow 3" kit to increase throttle response and turbo spool up by creating a full 3" intake tract from the intercooler outlet to the engine. Eliminates the angled OEM intercooler boots that are prone for failure. Includes FPRV Block off kit to allow proper clearance to larger diameter Y-bridge.
