Chevrolet Silverado 3500HD Intercooler Pipe - Passenger Side by Wehrli, 3.5 inch High Flow, Candy Red (2020–2024). A one-piece 14 ga aluminum cold-side pipe that replaces the factory plastic two-piece on the 6.6L L5P Duramax.

Built to manage higher boost, it uses a CNC-machined flange with double O-rings, an upgraded silicone boot, and a black anodized billet adapter to help stop blown boots and leaks. A threaded bung accepts the OEM intake temp sensor, and the direct-fit layout needs no extra mods or tuning. Candy Red powder coat and stainless T-bolt clamps deliver durable, bolt-on performance.
