Chevrolet Duramax Intercooler Pipe Kit - Driver Side - Wehrli - 3" High Flow - Bengal Red - '20-'25. This Wehrli driver-side 3" high-flow intercooler pipe replaces the factory two-piece 2.5" setup with a durable one-piece 3" pipe designed for the 2020–2025 L5P Duramax.

Built as a direct-fit bolt-on for stock trucks, this pipe improves airflow capacity over the factory piping while using upgraded silicone boots rated for higher pressure and temperature to reduce the risk of blown factory boots. The one-piece construction reduces joints and potential leak points, and the included T-bolt clamps ensure a secure connection. Finished in custom single-stage Bengal Red powder coat, it offers a durable surface that resists chips and corrosion without affecting fitment. No tuning or other modifications are required for installation.
