The Wehrli Custom Fab driver-side 3" high-flow intercooler pipe replaces the restrictive OEM 2.5" piece on 2004.5–2010 Chevrolet Duramax LLY/LBZ/LMM engines, increasing diameter to a full 3" to improve airflow between turbo and engine. The design avoids the OEM reverse bead roll at the turbo that can slip under higher boost. Includes high-pressure silicone boots, T-bolt clamps and a custom powder coat finish for durability and a secure fit where the OEM part was prone to failures.
