Make a bold statement under the hood of your 2020 and newer Chevrolet 6.6L L5P Duramax with the Wehrli Custom Fabrication 3.5-inch Intake Horn with PCV Port in WCFab Red. This high-performance billet aluminum replacement for the OEM rubber intake elbow maximizes airflow at the turbocharger inlet — reducing restriction, improving turbo spool time, and delivering a more responsive driving experience whether you're towing, hauling, or putting miles on the highway.
The WCF100833-RED is finished in Wehrli's signature WCFab Red — a bold, recognizable color synonymous with performance diesel upgrades. The built-in PCV port handles crankcase ventilation without any additional fittings or hoses.
