Wehrli 06-10 GM LBZ/LMM Duramax Passenger Side Intercooler Outlet Elbow Kit - Gloss Black
Improve turbo efficiency and reduce intercooler backpressure on your 2006–2010 GM LBZ or LMM Duramax diesel with the Wehrli Custom Fabrication Passenger Side Intercooler Outlet Elbow Kit in Gloss Black. This precision-fabricated aluminum elbow replaces the restrictive factory intercooler outlet tube, improving charge air delivery to the intake manifold and helping your Duramax breathe better at any boost level.
Wehrli's intercooler outlet elbow is mandrel-bent from high-grade aluminum for a smooth, turbulence-free airflow path. The Gloss Black powder coat provides a clean, stealth appearance while resisting the extreme heat and vibration found on a turbocharged diesel. All silicone couplers and T-bolt clamps are included for a leak-free, bolt-on installation.
