The Wehrli 3" driver-side intercooler pipe is made for 2004.5–2010 Chevrolet 6.6L Duramax LLY/LBZ/LMM models and replaces the smaller OEM piping with a full 3" high-flow tube. Built to eliminate weak factory bead-roll connections, it uses straight high-pressure silicone boots and t-bolt clamps to resist boost leaks under higher boost levels while improving airflow between turbo and intercooler.
