BMW 428i Air Filter - Dinan - High Flow Drop-in Replacement - '14–'16. A direct, high-flow upgrade for your factory air box that improves breathing and serviceability.

Dinan’s drop-in filter uses four layers of oiled cotton gauze to cut pressure drop versus stock paper, helping the N20/N26 draw air efficiently without sacrificing filtration. It’s washable and reusable to reduce long-term costs, and installs quickly in the OEM air box—great on its own or as a base for later intake changes.
