Description

The Wehrli Custom Fabrication L5P High Flow Cast Turbo Intake Horn is a direct replacement for the restrictive OEM plastic turbo mouthpiece on 2017-2026 Chevrolet Silverado and GMC 2500/3500 HD trucks with the 6.6L Duramax Diesel engine. It offers increased airflow to the turbocharger for improved engine performance and throttle response. This horn is constructed from CNC machined cast aluminum and features a #10 ORB threaded billet aluminum hose barb for PCV connection.
