Description

This 3.5" cold side intercooler pipe kit for 2020-2025 L5P Duramax engines replaces the factory passenger side intercooler pipe, which is prone to failure due to its crimped ends and restrictive design. The Wehrli Custom Fabrication (WCFab) pipe features a smooth, mandrel-bent design for improved airflow and durability. It is compatible with both factory and most aftermarket cold air intakes, and includes the intercooler pipe, silicone boot, and T-bolt clamps.
