Chevrolet Duramax Intercooler Pipe - Passenger Side - Wehrli - 3.5 in. High Flow - Bengal Red - `20-`25 is a direct-fit passenger side cold-side intercooler pipe designed for 2020–2025 L5P Duramax trucks. This one-piece 3.5" aluminum pipe replaces the factory two-piece plastic design for improved durability and sealing.

Built from 14 gauge aluminum with a CNC-machined flange and double O-ring seal, this Wehrli pipe is intended to withstand higher boost pressures than the stock components and reduce the chance of blown boots and boost leaks. It uses an upgraded silicone boot with a black anodized billet aluminum adapter and stainless steel T-bolt clamps in place of the OEM clip ring. The pipe includes a threaded bung to reinstall the OEM intake air temperature sensor and ships with a new intercooler outlet retaining clip. Powder coated in Bengal Red, it installs on stock trucks with no additional tuning or modifications required.
