WCFab High Flow 3in Y-Bridge Kit for Select 2001-2004 Chevrolet/GMC (6.6L LB7) - WCFab Red

Fits select 2001-2004 Chevrolet Silverado and GMC Sierra 2500 HD and 3500 models (6.6L LB7 Duramax).

The WCFab High Flow 3-inch Complete Y-Bridge Kit is engineered to resolve the primary airflow restrictions in the LB7 intake tract. This kit replaces the narrow factory Y-bridge and restrictive cold-side intercooler pipe with a full 3-inch system, increasing airflow by up to 50% over the OEM components. By streamlining the path from the intercooler outlet to the engine, this kit significantly improves throttle response and turbo spool-up.

Designed for versatility, this fabricated billet Y-bridge is compatible with the factory IHI turbocharger as well as aftermarket drop-in IHI-style chargers. The kit also eliminates the angled OEM intercooler boots, which are known failure points under increased boost. Every component is finished in a durable WCFab Red powder coat for long-lasting corrosion resistance and a custom look.
