Fits: 2006 thru 2007 Chevy Silverado/GMC Sierra 2500HD/3500HD LBZ Duramax Diesel

Wehrli Custom Fabrication's 3" LBZ Y-Bridge Kit is an upgraded high flow intake kit which replaces the OEM upper intake manifold supplying air to the engine intake runners. OEM Y-bridges for these trucks are a poorly designed, slip-fit style two piece bridge with very little support. They are prone to blowing apart under boost on hard working/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.

• High flow two-piece Y-bridge
• Mandrel bent smooth flowing intercooler pipes
• CNC machined billet flanges
• Compatible with OEM passenger lower intercooler pipe or WCFab 3.5" high flow
