OEM Air Filter - E30, E36, E34, E32, E31 (M20, M42, M70)

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 M20, M42, and M70 engines and the stock air box in the E30 318i/325e/325i, E36 318i, E28 528e, E34 525i M20, E32 750iL, and E31 850i/850ci/850CSi.
