Product Description

WCFab 3” High Flow Passenger Side Intercooler pipe for the LBZ/LMM Duramax (2006-2010). This inter cooler pipe replaces the factory passenger side inter cooler pipe and removes the restrictive grid heater and throttle blade assembly. It bolts to the factory Y-Bridge with a leak free O-ring seal. The Pipe uses two heavy duty braces to support the factory bridge in place, but it is NOT recommended for use in applications with upgraded turbochargers and higher boost levels. We recommend our full 3″ Y-bridge Kit for those applications.

Note: a Modified up pipe or our 2″ Stainless up pipe kit will be necessary to complete the install.

Note: 2010 Model requires a Map Sensor Seal and Bracket, sold separate.

Contents of Kit;

  • 3” High Flow Passenger Side Intercooler Pipe
  • O-Ring
  • Heater hose and clamps for coolant line (LBZ Only)
  • Powder Coating color of choice (Basic Colors)
