Details

Ready to rule out the possibility of blowing out your factory Y-bridge under high boost? This is Wehrli Custom Fabrication’s most affordable 3-inch Y-bridge option. It replaces the stock Y-bridge with a higher flowing, modified factory version that is much more durable. The larger 3-inch diameter unit can add as much as 20-30 horsepower over the restrictive factory piece.

This LB7 Y-bridge is designed for stock turbo trucks, works with either the factory or a 3½-inch intake horn, and carries a $100 core charge. Note: you will need to supply your own 3-inch outlet cold side (passenger) intercooler pipe, modify your factory one (2.5-inch outlet, stock), or order a brand new, fully fabricated Wehrli Custom Fabrication unit (found here) with this kit. Y-bridges are powder coated in the color of your choice (see available color options in the chart below, and make your color selection in the drop down menu above). Please specify the model year of your truck (this helps us determine the placement of the MAP sensor).

 

Kit Includes:

  • *3-inch diameter fabricated Y-bridge assembly
  • *TIG welded
  • *One 1/8-inch bung
  • *Silicone boots and clamps
  • *Powder coated the color of your choice
  • *Core charge
  • Approximate install time: 6 hrs
