BMW B58 Intake (G Series) – Boosted Engineering

Improve airflow, turbo response and induction sound with the Boosted Engineering B58 High Flow Intake System.

Designed for BMW B58 applications, this intake system reduces restriction compared to the factory airbox while significantly amplifying intake and blow off noise for a more aggressive driving experience. Expect increased turbo spool sound, intake tone and throttle response, particularly under load and during gear changes.

Suitable for both stock turbo and upgraded turbo applications.

No tuning is required for installation, however additional performance gains may be achieved with appropriate ECU calibration.
