Wehrli 01-04 Chevrolet 6.6L LB7 Duramax 3in Y-Bridge Kit - Candy Blue

High-flow 3" complete Y-Bridge kit for LB7 Duramax, compatible with factory IHI turbo and aftermarket drop-in IHI-style chargers. Replaces restrictive OEM Y-bridge and cold side intercooler pipe, creating a full 3" intake tract for increased throttle response and turbo spool-up. Eliminates angled OEM intercooler boots prone to failure. Includes FPRV Block off kit for clearance.

NOT RECOMMENDED FOR USE WITH S300 OR S400 STYLE TURBOCHARGERS. WILL NOT FIT WITH A BANKS INTERCOOLER (use WCF100640). For non-factory turbos, minimum T4 pedestal height required: 5" for S300, 6" for S400. 2001 models require relocating the MAP sensor to the new bridge, then drilling and tapping the original MAP port for a pipe plug (not included) or sourcing an 02-04 LB7 intake runner.
