Wehrli’s driver-side 3-inch intercooler pipe for 2011–2016 Duramax LML diesels replaces the factory two-piece 2.5-inch pipe with a single-piece 3-inch construction to boost airflow. It comes with upgraded silicone boots and T-bolt clamps to improve pressure resilience and durability under higher temperatures, and it fits factory or drop-in turbos to help reduce boot failures and support enhanced charge flow.
