Description

The Wehrli Custom Fab WCF100535-CR 4" Turbo Intake Horn is a candy red intake horn designed to replace the restrictive stock turbocharger intake on GM 6.6 Duramax LB7 engines. It increases airflow to the turbocharger for improved engine performance and throttle response.

This intake horn is constructed from precision CNC machined cast aluminum and features a candy red powder coat finish. It includes mounting hardware and an O-ring seal at the face of the turbocharger. The design provides a true 4" inlet with a smooth transition to the turbo compressor cover for optimized airflow and drivability.
