WEHRLI WCF100712 2001-2004 LB7 DURAMAX STAGE 3 HIGH FLOW INTAKE BUNDLE KIT

The WEHRLI WCF100712 2001-2004 LB7 DURAMAX STAGE 3 HIGH FLOW INTAKE BUNDLE KIT by WCFab is the ultimate solution for enhancing the performance of your 2001-2004 LB7 Duramax engine. This Stage 3 upgrade combines WCFab's Stage 1 High Flow Bundle, Stage 2 Intake Kit, and 3" Down Pipe into one comprehensive package, ensuring increased airflow to your turbo and engine for improved efficiency, throttle response, and turbo spool up.

This kit revolutionizes your LB7 Duramax by replacing the restrictive OEM Y-Bridge, intercooler pipes, and down pipe with high-flow 3” mandrel bent aluminum piping. The result is a full 3" intake tract that boosts throttle response, turbo spool up, and reduces EGTs, thanks to WCFab's signature TIG welded, CNC machined billet y-bridge base.

Crafted from fabricated aluminum, the air intake pipe and air box enclosure feature a dry filter assembly that outperforms the factory plastic parts. The all-aluminum construction includes large diameter 4" piping with smooth bends for increased intake air velocity, horsepower, torque, and a more aggressive engine and turbo sound during acceleration.

The High Flow 3.5 in. Turbo Intake Horn further enhances turbo performance, removing restrictions for improved spool and power. The kit also includes upgraded silicone boots for increased reliability and to prevent boost leaks, along with a Fuel Pressure Regulator Valve (FPRV) Block Off Kit for clearance to the Y-Bridge assembly.

For the finishing touch, the components are coated in Black Ceramic Coat with Heat Wrap. Moreover, there is an array of custom powder coat colors available to match your truck's aesthetic. The high-quality powder coating process guarantees a durable, corrosion-resistant finish that lasts longer than traditional paint coatings. With over 30 different colors in stock and additional options available, you can customize your LB7 Duramax engine with a unique and vibrant look.

Upgrade your LB7 Duramax engine with the WEHRLI WCF100712 Stage 3 High Flow Intake Bundle Kit by WCFab for improved performance, efficiency, and style.
