Product Description
Improve airflow efficiency and eliminate restrictive factory piping with the WEHRLI CUSTOM FAB WCF100328 PASSENGER SIDE UPPER CROSSOVER INTERCOOLER PIPE KIT for the 2011-2016 LML Duramax. Designed and fabricated by Wehrli Custom Fabrication, this high-performance intercooler pipe upgrade replaces the factory passenger side upper charge pipe with a stronger, smoother flowing mandrel-bent aluminum design.
The OEM LML intercooler piping is known to create airflow restrictions and can become a weak point on higher boost applications. The Wehrli WCF100328 pipe kit improves airflow from the intercooler to the intake system while providing increased durability under high boost conditions. Constructed from precision-formed aluminum and paired with high-quality silicone boots and stainless clamps, this kit provides improved reliability for both tuned street trucks and high horsepower performance builds.
