Wehrli's 3.5" passenger-side intercooler pipe for 2020–2025 Duramax L5P swaps the fragile OEM two-piece plastic pipe for a one-piece 14 ga. aluminum design with a CNC-machined flange, double O-rings and upgraded silicone boot. The billet adapter and robust clamps help resist boost leaks and blown boots. Designed for stock trucks, it installs without additional tuning or modifications.
