Wehrli Custom Fab 3" Y-Bridge kit for 2001-2004 Chevrolet 6.6L LB7 Duramax replaces the restrictive OEM Y-bridge and cold-side intercooler pipe to create a continuous 3" intake tract from the intercooler outlet to the engine, improving throttle response and turbo spool-up. Delivering about 50% more airflow than the OEM upper intake, the kit includes a 3" mandrel-bent passenger-side pipe, fabricated billet Y-bridge, O-ring flange gaskets, silicone boots, stainless T-bolt clamps, MAP sensor seal, hold-down bracket and FPRV block-off kit. Powder-coat finish in Bengal Silver; made in USA.
