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

Wehrli Custom Fabrication's 3" Y-Bridge Kit replaces the OEM upper intake manifold supplying air to the engine intake runners. The OEM Y-bridge for these trucks is a poorly designed, slip-fit style two-piece bridge with very little support and is prone to blowing apart under boost which creates poor drivability, reduced fuel economy, 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.

Features:

• High flow two-piece Y-bridge, flows 36% better than stock
• Mandrel bent smooth flowing intercooler pipes
• CNC machined billet flanges
• 14ga. aluminum intercooler piping
• Improve efficiency, throttle response & turbo spool-up
• Withstand higher boost pressures & increase reliability
• Eliminates restrictions and known failure points in OEM design
• No tuning required, no other modification or upgrades needed
• Compatible with stock trucks
• Made in the USA

• WCFab Signature 3" two piece Y-bridge
