Enhance performance and underhood aesthetics on your 2017-2019 Chevrolet 6.6L L5P Duramax with the Wehrli Custom Fabrication 3.5-inch Intake Horn with PCV Port in WCFab Red. This direct-fit billet aluminum intake horn replaces the factory connection between your intake tube and turbocharger inlet, eliminating the restriction and turbulence of the OEM rubber elbow for measurably improved airflow and throttle response.
The WCF100721-RED is finished in Wehrli's iconic WCFab Red powder coat, offering a bold, high-visibility look that stands out in any engine bay. The integrated PCV port ensures your crankcase ventilation system continues to function correctly without modification.
