Wehrli 06-10 GM LBZ/LMM Duramax Passenger Side Intercooler Outlet Elbow Kit - WCFab Red
Add bold performance style and improved airflow to your 2006–2010 GM LBZ or LMM Duramax with the Wehrli Custom Fabrication Passenger Side Intercooler Outlet Elbow Kit in WCFab Red. This mandrel-bent aluminum elbow replaces the factory intercooler outlet tube for a larger, smoother bore that delivers cooler, denser charge air to your intake manifold — supporting better horsepower, lower EGTs, and improved throttle response.
Wehrli's WCFab Red is one of the most recognizable powder coat colors in the diesel performance industry, and this intercooler elbow wears it proudly. The finish is high-temp rated, chip-resistant, and built to look great through years of hard use. Complete with silicone couplers and T-bolt clamps for a direct, boost-leak-free install.
