High Flow Bundle Intake Kit Stage 2 01-04 Duramax LB7 Brizzle Blue

The WCFab 2001-2004 GM LB7 6.6L Duramax Stage 2 High Flow Intake Bundle Kit upgrades airflow to the turbo and engine, improving efficiency, throttle response, and turbo spool-up. It replaces restrictive OEM LB7 Y-Bridge, passenger, and driver side intercooler pipes with high-flow, 3” mandrel-bent aluminum piping and a TIG welded, CNC machined billet y-bridge base, creating a full 3" intake tract to reduce EGTs. The kit includes a fabricated aluminum air intake pipe and air box enclosure with a dry filter assembly, replacing plastic factory parts for improved horsepower, torque, and cooler intake temperatures. The air box is 10-gauge aluminum with a removable lid and hydrophobic pre-filter cover. It also features a High Flow 4" Turbo Intake Horn compatible with OEM and upgraded drop-in IHI style turbochargers, upgraded silicone boots for reliability, and an FPRV Block Off Kit for clearance. Available in custom powder coat colors.
