The Dodge Cummins Intercooler Pipe Kit - Driver Side - Wehrli - High Flow 3.5" Intake Horn - WCFab Red - `03-`07 is an essential upgrade for your 5.9L Cummins engine. Designed specifically for the 2003-2007 models, this kit ensures enhanced airflow and reliability with a robust construction and an aesthetically pleasing WCFab Red finish.

This upgrade replaces the prone-to-failure 3" plastic OEM intercooler pipe with a durable 3.5" heavy-duty 14g aluminum pipe. The OEM cast intake horn, which is narrowed to less than 1.5", is upgraded to a full mandrel bent 3.5" elbow for optimized air intake. This elbow is expertly welded to a CNC-machined aluminum mounting flange, complementing the WCFab Grid Intake spacer kit. This design ensures optimal air flow directly into the cylinder head, delivering up to 60% greater flow compared to the stock setup.
