Product Name:WC Fab High Flow Bundle Kit Stage 2, for 2006-2007 GM Duramax LBZ, Brizzle Blue
Manufacturer: WC Fab
Manufacturer Part #: WCF100437-BRZ
Thoroughbred Diesel Part #: WCF100437-BRZ
Fitment Notes: 2006-2007 GM Duramax LBZ

Stage 2 upgrade for the 2006-2007 LBZ Duramax combines our popular Stage 1 High Flow Bundle and Stage 2 intake Kit into a single package, providing increased airflow for your turbo and engine for improved efficiency, throttle response, and turbo spool up. Eliminates weak points in the factory design that can contribute to lost power, boost leaks, and complete failures in hard-working and high-performance applications.

On the air intake side, our high flow fabricated intake pipe, intake horn, and air box enclosure with dry filter assembly replaced the restrictive plastic factory parts on 2006-2007 LBZ Duramax Diesel for improved engine performance and sound. Significantly increases airflow to your turbo, producing improved horsepower and torque and cooler intake temperatures by drawing cold air through the inner fender. All aluminum 14 ga. construction features large diameter 4 in. piping with smooth aerodynamic bends. It improves intake air velocity volume and provides a more aggressive engine and turbo sound during acceleration. Our 4.8 in. turbo intake horn is the largest on the market providing a 20% air flow improvement over stock. High-quality hardware, silicone boot, seals, and stainless steel t-bolt clamps ensure optimum durability and ease of installation. Removable air box lid element allows for easy visual inspection and maintenance of your WCFab filter with included hydrophobic pre-filter cover, to help keep your MAF sensor, turbo, and engine airways contaminant free.

After the turbo, our Stage 2 kit also upgrades the restricted 2.5 in. diameter driver (hot) side intercooler pipe and leak-prone plastic/rubber passenger (cold) side pipe with WCFab's heavy duty 3 in. diameter 1-piece Driver (Hot) Side and 3.5 in. diameter Passenger (Cold) Side LBZ Intercooler Pipes. Made in the USA from high strength, heavy duty 14 ga. aluminum tube with smooth, aerodynamic mandrel bends for increased durability and optimized flow. 3 in. Driver Side pipe includes high quality reinforced silicone boots and stainless t-bolt clamps for superior temperature resistance and boost pressure holding capabilities. 3.5" Passenger Side pipe improves airflow over stock part by 47%! Features CNC machined flanges with double o-ring seals and an upgraded silicone hump boot to withstand higher boost pressures than the factory components to increase reliability and eliminate blown factory boots and horsepower-robbing boost leaks.

The final and key component of this bundle is our signature high flow 3" Y-Bridge Kit, which replaces the OEM upper intake manifold supplying air to the engine intake runners. The OEM Y-bridge for these trucks is a poorly designed, slip-fit style two-piece bridge with very little support and is prone to blowing apart under boost on hard working and high performance trucks creating poor drivability and decreased power. This kit is a much improved, high flow, bolt together style two-piece 3" bridge which provides a secure sealing surface where the air inlet horn connects to the bridge. 3" high flow upper and lower intercooler pipes feature smooth flowing mandrel bends, CNC machined billet flanges and perfectly compliment the y-bridge to offer a full 3" tract from intercooler pipe slip connection to the engine incorporating the factory grid heater and EGR connection controls for the ultimate in emissions compliant performance. 

Full assembly finished in your choice of WCFab's signature custom powder coat colors for a look as unique as your truck. Compatible with stock trucks, no tuning required. Saves $196 or MORE vs. purchasing included parts individually.
