AFe Pro5R Air Filter – E36/Z3 4 Cylinder – 318i 318is 318ti & Z3 1.9

Product Details

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:

E36 3 series : 318i 318is 318ti
Z3 : Z3 1.9

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.
