This is a drop-in stock replacement aFe performance air filter that installs into your BMW's factory airbox. This particular filter fits the following BMWs:
E30 M3 (1988-1991)
E30 318i (1984-1985)
E28 528e (1984-1985) and 535i/535is (1985-1988)
E12 5 series, All (1975-1981) - including 528i, 530i, 533i
E23 7 series, All except 745i (1977-1987) - including 730i, 733i, 735i, L7
E24 6 series, All except M6 (1976-1989) - incl. 630CS, 633Csi, 635CSi


This version uses aFe's highest flowing filter media, which uses a lightly oil gauze to filter out dirt and particulates, while allowing more air to flow to the intake. For the best flowing filter, with the best performance gain, we always recommend this standard aFe filter media (often called "Pro5R ", which has a blue pre-oiled filter media). We also carry this filter in the "ProDry" grey filter media, which is oil-free for only slightly less performance and no maintenance.
