Improve airflow to your 2020+ Chevrolet 6.6L L5P Duramax without replacing the entire air box with the Wehrli Custom Fabrication 4-inch Intake Pipe in WCFab Red. Designed to work with your factory OEM air box, this larger-diameter intake tube dramatically increases air volume delivered to your turbocharger compared to the restrictive factory unit.
Precision-crafted from 14-gauge mandrel-bent aluminum and finished in Wehrli's signature WCFab Red powder coat, the WCF100720-RED delivers a bold appearance with real performance benefits. The 4-inch upgrade reduces intake restriction for improved turbo spool and increased power across the RPM range.
