Wehrli’s passenger-side 3.5" intercooler pipe for 2020–2025 Duramax L5P upgrades the factory plastic two-piece to a one-piece 14‑ga. aluminum pipe to improve airflow and reliability. A CNC‑machined flange with double O‑rings and a silicone boot with black anodized billet adapter prevent boost leaks under higher pressures. The pipe includes a threaded bung for the OEM intake temperature sensor, stainless steel T‑bolt clamps, and a durable powder coat. Fits stock trucks as a direct bolt‑on without tuning.
