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.

***NOTE: WILL NOT FIT WITH A BANKS INTERCOOLER. If you have a Banks intercooler, please call us for help placing your order.***

***NOTE: NOT RECOMMENDED FOR USE WITH S300 OR S400 STYLE TURBOCHARGERS. If you are planning to run a turbo other than an OEM / IHI style upgraded drop in on your setup, please check out our S300 Single Turbo Kit WCF100478 and our S400 Single Turbo Kit WCF100489 or call us for help placing your order.***
