Description

The WCFab Y-Bridge Kit is the only high-flow 3" complete Y-bridge kit for the LB7 Duramax that is compatible with factory IHI turbos and aftermarket drop-in IHI style chargers. It replaces the restrictive OEM Y-bridge and cold side intercooler pipe with a 3" intake tract from the intercooler outlet to the engine, increasing throttle response and turbo spool-up. It also eliminates angled OEM intercooler boots prone to failure and includes an FPRV Block off kit for clearance.
