BMW F2X/F3X B46/B48 Intake System by CTS Turbo

Unlock the B46/B48 turbo four in your BMW F2X/F3X 230i, 330i or 430i with the CTS Turbo high-performance intake. It replaces the restrictive stock airbox so the engine breathes freely, delivering real horsepower and torque gains, sharper throttle response and an aggressive turbo sound. A high-flow, reusable washable filter feeds maximum airflow, while a custom-fit heat shield keeps intake air temperatures low for consistent, reliable performance.
