Product Description
Improve charge-air flow and reduce restriction with the WEHRLI CUSTOM FAB WCF100353 DRIVER SIDE 3IN INTERCOOLER PIPE for the 2011-2016 LML Duramax platform. The factory driver-side charge pipe on LML trucks is restrictive and prone to failure under higher boost levels. Wehrli Custom Fabrication engineered this upgraded 3-inch aluminum intercooler pipe to deliver increased airflow, improved durability, and better turbo efficiency.
Constructed from high-quality mandrel-bent aluminum tubing, this pipe replaces the factory unit with a larger diameter design that improves airflow between the intercooler and engine intake system. The result is improved boost response, better efficiency under heavy load, and increased reliability for trucks running upgraded tuning, turbochargers, or heavy towing conditions.
