Chevrolet Silverado 2500 HD Intercooler Pipe - Passenger Side - Wehrli - 3.5 in. - Illusion Blueberry - 2017-2019. This high-flow cold-side pipe replaces the fragile factory two-piece plastic with a robust, powder-coated aluminum upgrade.

Built from 14 ga aluminum in a single 3.5 in. tube, it improves airflow and durability. A CNC machined flange with double O-rings seals to the intercooler, while the upgraded silicone boot and stainless T-bolt clamps hold higher boost and help prevent leaks. It is a direct bolt-on for stock L5P 6.6L Duramax trucks with no tuning required, retains the OEM intake temperature sensor via an integrated threaded bung, and includes new O-rings and a wire clip. Replaces GM part 84189332. Not compatible with aftermarket intercoolers using a bead-roll outlet.
