Way Motor Works has been using and installing DDMworks intakes on MINIs for years now. But with the R56 and newer MINIs having Mass airflow sensors we never liked the idea of the oiled filters and chance the oil could get in the sensor. So WMW had new high flow dry no oil filters custom made to fit the DDMworks intakes. These new air filters are still high flow and fit perfect while giving you that cool intake sound. If you already have a DDMworks intake you can order just the filter for an upgrade. HERE WMW will have these standard on the R56 Street intakes. DDMWorks R56 Street Intake - Way Motor Works and an option on all other DDMworks intakes. DDM Works - Way Motor Works Right now these are exclusive to Way Motor Works, but DDMworks may start directly stocking them later.
