Product Details

The Wehrli Custom Fabrication High Flow 3" Y-Bridge Kit is an upgraded intake system designed specifically for 2006-2007 LBZ 6.6L Duramax diesel engines. This performance kit replaces the restrictive OEM upper intake manifold with a complete bolt-together solution that delivers improved airflow and eliminates common failure points.

Superior Design Over Stock:

The factory Y-bridge on LBZ Duramax trucks uses a poorly designed slip-fit two-piece design with minimal support, making it prone to separation under boost pressure on hard-working and high-performance applications. This causes loss of power and poor drivability. The Wehrli kit features a robust bolt-together two-piece 3" bridge with secure sealing surfaces and proper support throughout.

Complete High-Flow Kit Includes:

  • WCFab Signature 3" two-piece Y-bridge with CNC machined billet flanges
  • 3" upper intercooler crossover pipe with smooth mandrel bends
  • 3" lower intercooler pipe
  • High-quality silicone boots and stainless steel T-bolt clamps
  • MAP sensor seal and high-temp O-ring seals for grid heater and EGR
  • Y-bridge O-ring flange seals and new up-pipe to EGR gasket
  • New grid heater installation hardware
  • Custom powder coat finish in your choice of colors

Key Performance Benefits:

  • 36% improvement in airflow over stock components
  • Eliminates known OEM restriction and failure points
  • Full 3" flow path from intercooler connection to engine intake runners
  • Retains factory grid heater and EGR connection controls
  • No tuning required - direct bolt-on installation
  • Compatible with stock trucks without additional modifications

Proudly manufactured in the USA with precision CNC machining and state-of-the-art fabrication equipment. Each kit is finished with a durable custom powder coat for both performance and show-quality appearance. Compatible with OEM lower passenger side intercooler pipe as well as Wehrli's upgraded 3.5" high-flow passenger side intercooler pipe kit for maximum performance gains.

good price easy checkout

I had ordered some CM-19546-A2 (friction-modifier for posi-traction differentials with carbon-fiber clutches) from CJ Pony Parts, and it arrived broken and had all leaked out. I spent $25.42 for nothing, and they still have not responded to my complaint. I bought 2 bottles from THMotorsports in hopes that ONE would arrive undamaged. They arrived in a box, not a bubble mailer like CJ, and both bottles were intact and undamaged. If you're going to buy specialty automotive fluids online, THMotorsports is the better place to do so.

SO FAR THE CHECKOUT WAS GOOD-WE WILLSEE HOW IT GOES WHEN I RECIEVE THE BUMPER

Thanks

First time so ...

Great,fast,convenient

The purchase is good but I need the tire to arrive to give them a better opinion
