Wehrli Custom Fabrication WCF100412-CR High Flow Turbo Intake Horn Candy Red

The Wehrli Custom Fabrication WCF100412-CR is a high-flow cast aluminum turbo intake horn finished in a striking Candy Red custom powder coat. Engineered to replace the restrictive OEM plastic inlet, this performance upgrade delivers a significant boost in airflow to the turbocharger for improved throttle response and overall engine performance.

Built from CNC machined cast aluminum, this intake horn features a massive 4.8-inch inlet — the largest intake horn on the market — providing a 20% improvement in airflow over stock. The redesigned inlet path eliminates the factory resonator connection, freeing up airflow restrictions while giving your engine bay a cleaner, more aggressive look and sound.
