Description

The Wehrli WCF100721-FB is a High Flow Cast Turbo Intake Horn designed for 2017-2026 L5P Duramax trucks. It replaces the restrictive OEM plastic turbo mouthpiece, increasing airflow to the turbocharger for improved engine performance and throttle response. This intake horn is constructed from CNC-machined cast aluminum and features a billet aluminum port for PCV connection. It is compatible with stock and OEM-style aftermarket turbochargers and works with both OEM and aftermarket cold air intake systems.
