This is the Genuine BMW air filter for the B46 engine in the G42 230i, G20 330e, 330i, G22 430i, G29 Z4 30i.
Since the quality of the intake air has a direct affect on performance and efficiency it just makes sense to have a clean air filter. Clogged and dirty filters will prevent good airflow to the engine and the engine computer has no choice but to compensate. To help keep your engine running at its optimum best, always replace or clean your air filter once a year.
