GMC Sierra 2500 HD Intercooler Pipe - Passenger Side - Wehrli - 3.5 in. - Illusion Blueberry - 2017-2019. This high-flow, one-piece cold-side pipe replaces the factory plastic section on L5P 6.6L Duramax models for improved durability and consistent boost control.

Built from 14 ga aluminum with a durable Illusion Blueberry powder coat, this 3.5 in. WCFab pipe features a CNC-machined flange with double O-rings, a reinforced silicone boot, and stainless T-bolt clamps to help reduce boost leaks and blown boots. It retains factory functionality with a threaded bung for the OEM intake temperature sensor, includes new O-ring seals and a wire clip for the intercooler outlet, and installs on stock trucks with no tuning or other modifications. Not compatible with aftermarket intercoolers that use a bead-roll style outlet.
