Chevrolet Duramax Performance Air Intake - Wehrli - 3in Y-Bridge Kit - Sparkle Granny Smith - 06-07. Built for the 2006-2007 LBZ, this WCFab kit replaces the restrictive factory upper intake with a robust, high-flow 3-inch system finished in Sparkle Granny Smith.

The OEM slip-fit Y-bridge can separate under boost, hurting drivability. WCFab's bolt-together 3-inch two-piece Y-bridge and matching 3-inch intercooler pipes use mandrel bends and CNC billet flanges to keep a full 3-inch tract from intercooler to engine, while retaining the factory grid heater and EGR connections. It's bolt-on for stock trucks with no tuning required, and mates to the OEM lower passenger-side pipe or WCF100367 3.5-inch upgrade. Includes silicone boot, stainless T-bolt clamps, MAP seal, O-rings, up-pipe to EGR gasket, and grid heater hardware.

• WCFab 3-inch two-piece Y-bridge
