aFe Pro 5R Performance Air Filter - G42 M240i, G20 M340i, G22/G26 M440i, G29 Z4 M40i, Supra

aFe performance air filter replaces BMW part #13718635102 for G42 M240i, G20 M340i, G22/G23/G26 M440i, G29 Z4 M40i, and A90 Supra (#17801WAA01).

afe Pro 5R panel filter is a direct replacement for the original paper filter in your stock air box. If you're looking for a power gain and improved throttle response but without the accompanying cost and noise of a full intake kit, a replacement filter is the solution. The Pro 5R is an oiled-cotton gauze filter media - the 5-layer filter flows a lot better than the stock filter while a small coating of retention oil traps dirt, dust, and debris. The Pro 5R filter is washable and reusable and only needs occasional cleaning and re-oiling from an aFe service kit. 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.
