Wehrli's 3" high‑flow driver side intercooler pipe for 2020–2025 L5P Duramax replaces the factory two‑piece 2.5" assembly with a one‑piece 3" pipe and upgraded silicone boots. The kit increases reliability by resisting higher pressures and temperatures, uses t‑bolt clamps and silicone boots, and installs as a bolt‑on without tuning, addressing common blown‑boot failures on stock trucks.
