Wehrli 01-04 Duramax LB7 Stage 1 High Flow Intake Bundle - WCF100411-BCFind parts that fit my vehicle

The OEM components between the turbo and engine? Check out the WCFab Stage 1 High Flow Intake Bundle Kit for the 2001-2004 6.6L Duramax. This kit replaces the restrictive OEM LB7 Y-bridge, passenger side intercooler pipe, and driver side intercooler pipe with a high flow, 3” mandrel bent aluminum piping kit feeding WCFab's signature TIG welded, CNC machined billet y-bridge base to help increase throttle response, turbo spool up, and reduce EGTs by creating a full 3" intake tract between your turbo and engine.

Air intake systems are a common first mod to many project cars. They are quick and simple to install while also enhancing the looks of your engine bay, the sounds of your engine, and the performance of your vehicle.

We often recommend upgrading your OEM intake to a cold air intake as one of the first modification your should do to your car. Often times, the factory airbox is restricting. Replacing your intake system with an aftermarket unit will increase intake noise, performance, and improve your overall driving experience.

Pop the hood on a diesel enthusiast's truck somewhere in North America and you may find my company's logo on the engine. Welded to an intake or intercooler pipe, this logo represents an awesome responsibility to the diesel enthusiast community that has supported WCFab over the years. It's a responsibility and commitment to ensure WCFab products meet the highest standard of craftsmanship and fitment. We care enough to put our name on it.
