A CNC machined flange with double O-rings enhances sealing to help prevent boost leaks, while the upgraded silicone boot and stainless T-bolt clamps hold higher boost than stock. It includes a threaded bung for the OEM intake temperature sensor, O-ring seals, and a new wire clip. Durable Illusion Blueberry powder coat. Direct bolt-on for stock intercooler systems; no tuning required. Replaces GM 84189332. Not compatible with aftermarket intercoolers using a bead-roll outlet.
