The Wehrli driver-side 3" hot-side intercooler pipe is made for 2004.5–2010 Chevrolet 6.6L Duramax LLY/LBZ/LMM applications and replaces the restrictive OEM 2.5" piping with a full 3" tube. The design avoids the OEM reverse bead roll at the turbo, using straight high-pressure silicone boots, T-bolt clamps and a single-piece construction with custom powder coat in Cat Yellow for improved boost reliability.
