The Wehrli high‑flow 3" driver‑side intercooler pipe for 2020–2025 L5P Duramax replaces the factory two‑piece 2.5" intercooled pipe with a one‑piece 3" unit and upgraded silicone boots. The heavier‑duty aluminum pipe and reinforced boots better withstand pressure and heat to reduce boost leaks and eliminate blown factory boots, and it installs on stock trucks without additional tuning.
