aFe Pro5R Air Filter - E30 1986-1991 (no M3), 86+ 528e, E34 525i (M20), E32 750iL (x2) (more info)

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 3 series: 318i, 318is 318i Convertible 1990-1991
E30 3 series: 325e, 325es 1986-1988

E28 5 Series: 528e 1986-1988
E34 5 Series: 525i 1989-1990
E32 7 Series: 750il 1988-1994 (requires 2 of these filters).

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.

No-Toil Foam Filter Oil (for ITG Filters) (more info)

Don't use harsh solvents like gasoline to clean your ITG on your Eurosport/Conforti intake kit (or similar foam filter element). This product is all you need to maintain your ITG foam filter, and is recommend for use with all Conforti Cold-Air Intake Kits.

When cleaning an ITG foam filter, ITG recommends using warm water and a mild detergent (simple dish soap is fine). Strong detergents and solvents can harm the foam, and cause the filter to break down. Once dirt, dust and debris are rinsed out of the filter, it should be re-oiled to ensure proper function of the filter. ITG recommends No-Toil filter oil, as it is safe to the foam filter media, and is completely waterproof. Drive with more peace of mind through heavy rain and puddles.

Please note, as this product is an aerosol, it MUST BE SHIPPED BY UPS GROUND. Sorry, this can not be shipped outside of the US/Canda.
