Driver Side Intercooler Pipe

The Wehrli Custom Fabrication Driver (Hot) Side 3" Intercooler Pipe is engineered to replace the restrictive factory two-piece 2.5" piping on 2011-2016 GM 6.6L Duramax LML engines. This upgraded one-piece 3" pipe enhances airflow, leading to improved durability and reliability, especially under higher boost conditions. The pipe itself is constructed from 3" diameter tubing and is mandrel-bent for a smooth, unrestricted flow path. Key benefits include improved airflow over the stock pipe, increased reliability due to the one-piece design, and the elimination of blown factory intercooler boots. The pipe is compatible with both factory and drop-in style turbochargers and is designed as a direct-fit replacement. It directly replaces GM Part Numbers 23282450, 22739299, 22795678, 23122239, 22878220, 23461741, and 12757248.
