BMW 230i Performance Air Intake - Dinan - Carbon Fiber Semi-Open (2016-2021). This premium intake increases airflow, sharpens throttle response, and enhances turbo acoustics while maintaining everyday drivability.

Built around a larger airbox and filter, the Dinan system reduces restriction and helps the B46/B48 breathe more efficiently. An all-carbon fiber intake tube eliminates factory baffles and the Helmholtz chamber to smooth airflow, and the semi-open lid introduces a purposeful induction note. On a stock vehicle, testing has shown gains of up to 6 hp and 6 lb-ft at 5000 RPM. Durable carbon construction and improved coating help the intake look great and perform consistently over time. CARB EO D-176-56 applies to 2019-2021 230i/330i/430i only.
