Wehrli 06-10 GM LBZ/LMM Duramax Passenger Side Intercooler Outlet Elbow Kit - WCFab Grey
Boost intercooler efficiency on your 2006–2010 GM LBZ or LMM Duramax diesel with the Wehrli Custom Fabrication Passenger Side Intercooler Outlet Elbow Kit in WCFab Grey. This mandrel-bent aluminum elbow replaces the factory intercooler outlet tube to deliver better charge air flow to the intake manifold, improving turbo response and reducing charge air temps — especially under higher boost or heavy tow loads.
Wehrli's WCFab Grey powder coat is a signature color in the diesel performance world — distinctive and bold without being over the top. Paired with quality silicone couplers and T-bolt clamps, this elbow kit installs in minutes and offers a boost-leak-free seal right out of the box. Built in the USA to the same exacting standards as all Wehrli fabrication products.
