WCFab 3.5in Passenger Side Cold Side Intercooler Pipe for 2017-2019 Chevrolet Silverado/GMC Sierra (6.6L) - WCFab Grey

Fits 2017-2019 Chevrolet Silverado and GMC Sierra 2500 HD / 3500 HD models equipped with the 6.6L L5P Duramax engine.

The WCFab 3.5-inch High Flow Passenger Side (Cold Side) Intercooler Pipe addresses the common failure points of the factory charging system. This one-piece upgrade replaces the restrictive, multi-piece OEM plastic pipe with mandrel-bent 14-gauge aluminum tubing. By eliminating the factory clip-ring design in favor of a CNC-machined flange with double O-ring seals and heavy-duty silicone boots, this pipe provides a secure connection that withstands increased boost pressures without leaking or blowing off.

Designed for a seamless installation, this kit includes a threaded bung to retain your original Intake Air Temperature (IAT) sensor and requires no aftermarket tuning. It is a direct bolt-on replacement for GM part number 84189332, offering improved reliability and airflow for both stock and modified trucks.
