BMW M3 Air Filter Set - Dinan - High Flow Drop-in Replacement - '15-'18. A direct-fit pair of performance filters for the F80 M3, designed to improve airflow while maintaining excellent filtration.

Constructed with four layers of oiled cotton gauze, these Dinan filters reduce pressure drop compared to paper media so the S55 can breathe easier. They are washable and reusable, helping to lower long-term maintenance costs, and install quickly in the factory air boxes with no tuning required.
