Wehrli Custom Fab Stage Y-Bridge, Chevy/GMC (2001-04) 6.6L Duramax LB7

WCF100693
The only High Flow 3” Complete Y-Bridge kit on the market for your LB7 that is compatible with the factory turbo!
Also compatible with S300 or S400 single turbo install kits! Replace the restrictive OEM Y-bridge and cold side intercooler pipe with this high flow 3” kit to increase throttle response and turbo spool up by creating a full 3" intake tract from the intercooler outlet to the engine.
Eliminates the angled OEM intercooler boots that are prone for failure. Includes FPRV Block off kit to allow proper clearance to larger diameter Y-bridge.

NOTE: WILL NOT FIT WITH A BANKS INTERCOOLER. If you have a banks intercooler use Y-bridge kit WCF100640.
NOTE: If running a turbo other than factory a minimum T4 pedestal height with an S300 is 5" and with an S400 is 6" for proper clearance to Y-bridge.
NOTE: EGR equipped LB7 trucks will require a replacement passenger side up pipe.
