aFe Pro Dry S Performance Air Filter - F22 230i/M240i, F30 330i/340i, F32 430i/440i

aFe performance air filter replaces BMW part #13718632502 for F22 230i/M240i, F30 330i/340i, F32 430i/440i models.


aFe Pro Dry S panel filter is a direct replacement for the original paper filter in your stock air box. The synthetic filter material is denser than the aFe Pro 5R so it does not require any dust-retention oil, yet it flows up to 66% more air than a conventional stock paper filter. The Pro Dry S gives you a modest power increase with excellent filtration (99.2% efficiency) but less maintenance than the oiled filter. The Pro Dry S is cleaned using an aFe service kit and regular tap water. Since these OE-replacement filters sit inside your stock air box there is no change to intake noise or factory appearance of your engine bay.

Notice of Emissions Non-Compliance. The intake system is part of a vehicle's emissions equipment. Removing, disabling, or altering emissions equipment on a pollution-controlled road vehicle violates federal EPA laws (regardless if it has no effect on emissions). Installing devices or software that trick, disable, or modify emissions controls and monitors on a pollution-controlled road vehicle is also illegal. It has been determined by the manufacturer that this product does not require a CARB Executive Order (waiver). However, because it is part of the emissions system it is not legal for installation or use on any pollution-controlled motor vehicle in any state, province, or jurisdiction governed by, or which has adopted, EPA regulations. Some suppliers will not ship to certain states, requiring extra delivery time. We will advise you of any delays.
