As the title suggest I've come across hengst oem z4mr airfilter & wondered if they are ok as they are cheaper than what the steeler sells them at. They are featured on eurocar parts web site & according to them are made in Germany.
Are they BMW oem or is the slight of hand wording in the sense they are oem size & shape.
Reason behind this is I've noticed my air filter does appear to be rather grubby and I have another 5k before the oil service.
