Description

Upgrade your Duramax’s performance and reliability with the SPELAB 3-Inch Y-Bridge and Cold Side Intercooler Pipe Kit. Designed for 2006–2010 6.6L LBZ and LMM Duramax engines, this kit replaces the restrictive factory plastic components with high-flow mandrel-bent aluminum pipes and reinforced silicone boots. The addition of a free-flowing Y-Bridge enhances throttle response, reduces boost drop, and ensures consistent airflow under heavy loads or performance tuning.

Key Features

  • Complete Cold Side & Y-Bridge Solution
    Includes a 3" cold-side pipe and high-flow Y-bridge to eliminate factory bottlenecks and improve boost control.

  • High-Strength Aluminum Construction
    Mandrel-bent aluminum pipes with a polished finish resist cracking and heat fatigue.

  • Reinforced Silicone Boots & T-Bolt Clamps
    Triple-layer silicone boots withstand extreme pressure and temperature, while constant-tension clamps provide leak-free sealing.

  • Improved Airflow & Durability
    Say goodbye to blown-out plastic pipes. This upgrade handles increased boost and temperature levels from modified or stock turbo systems.

  • OEM Fitment with Quick Installation
    Designed to fit with factory components—no cutting or tuning required.

Fitment

  • 2006-2007 6.6L LBZ Duramax Diesel (LBZ: 06-07 VIN Code 2 or D)
  • 2007.5-2010 6.6L LMM Duramax Diesel ( LMM: 07.5-10 VIN Code 6)

Needs Improvement

The Y-bridge is well made, but the cold side pipe isn't formed correctly. It should be bent tighter and lower. Also, the pipe should replace the intercooler connection, instead of making you reuse part of the factory pipe.

The color was not what I was expecting and it was a little tighter fit then I would have liked but it all fit and sounds nice
