Designed for 2011-2016 Chevrolet and GMC 6.6L LML Duramax trucks, this intercooler pipe is engineered to optimize airflow, enhance cooling efficiency, and provide a unique custom look. Replacing the stock pipe with this larger diameter unit is a smart move for performance-minded diesel enthusiasts.

Key Features:

  • Optimized Airflow: The 3-inch diameter significantly reduces restrictions, allowing for a greater volume of cooler air to reach the engine.
  • Unique WCFab Grey Finish: A stylish grey powder coat offers a custom, aggressive aesthetic that stands out.
  • Precision Fitment: Engineered as a direct replacement for the factory intercooler pipe on 2011-2016 LML Duramax models.
  • Performance Benefits: Helps lower Exhaust Gas Temperatures (EGTs), improves turbo spool, and enhances throttle response.
  • Durable Construction: Built with high-quality materials to ensure reliability under demanding diesel operating conditions.

This intercooler pipe is an excellent upgrade for anyone looking to push their LML Duramax further, whether for increased towing capability or enhanced performance on the street or track. Improved airflow management is key to unlocking the full potential of your diesel engine, and this pipe plays a vital role in that process. The WCFab Grey finish adds a personalized touch that complements other performance modifications. Choose Wehrli for dependable, high-performance diesel parts.
