aFe Pro Dry S Replacement Air Filter - E9X M3 2010-2013

aFe performance air filter replaces BMW part # 13727838804 for 2010, 2011, 2012, and 2013 E9X M3 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.
