aFe ProDry S Air Filter - E30 1986-1991 (no M3), 86+ 528e, E34 525i (M20), E32 750iL (x2)

This is a drop-in stock replacement aFe performance air filter that installs into your BMW's factory airbox offering significantly higher airflow than the stock paper filter. This particular filter fits the following BMWs:

E30 3 series: 318i 318is 1990-1991 - 318ic 1990-1993
E30 3 series: 325e 325es 325i 325is 325xi 325ic 1986-1991
E28 5 series : 528e 1986-1988
E34 5 series: 525i 1989-1990 M20 engine
E32 7 series : 750il 1988-1994 - 2 required
E31 8 series : 850i 850ci 850csi 1991-1999 - 2 required

This version has an oil-free filter media for less maintenance. For the best flowing filter, with the best performance gain, we always recommend the standard aFe "Pro5R " filter (which has a blue pre-oiled filter media), but this oil-free filter flows only slightly less than the blue Pro5R style aFe filter, and requires no re-oiling after cleaning the filter.
