Wehrli’s 3-inch driver-side intercooler pipe for 2011–2016 Chevrolet 6.6L LML Duramax swaps the factory two-piece 2.5-inch pipe for a single-piece 3-inch tube to increase airflow and reduce pressure drop. Upgraded silicone boots and T-bolt clamps are included to improve reliability under higher boost and temperature, and the pipe works with factory or drop-in style turbochargers without modification.
