GMC Sierra 2500 HD Intercooler Pipe - Driver Side - Wehrli - High Flow 3" - Candy Teal - ’17–’19. A direct-fit hot-side upgrade that replaces the factory two-piece pipe with a high-flow 3-inch unit.

Built by Wehrli Custom Fab for the 6.6L L5P Duramax (2017–2019), this driver-side intercooler pipe offers higher flow capacity and improved connection integrity versus the stock 2.5-inch assembly. The one-piece design reduces leak points, while premium silicone boots handle higher pressure and temperature. Stainless steel T-bolt clamps provide robust clamping, and the Candy Teal powder coat delivers durable protection. Fits stock trucks with no additional modifications or tuning required. Also replaces GM part number 87839947 and fits Chevrolet Silverado or GMC Sierra 2500/3500 HD.
