OEM Mahle Engine Air Filter - E21 E30 E28 E24 (M10, M30, S14)

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.

This is the OEM air filter for the M10 engine in the E21 320i (1980, 1981, 1982, 1983) and 1984-85 E30 318i, M30 engine in the E28 533i/535i and E24 633CSi/635CSi, and the S14 engine in the E30 M3.
