that's odd, they advertise new cabin filters on Ebay. However you just might be correct. I know the Z4 has one and I'm sure some versions of the Z3 has one. But it might be dependant on the age and model of your Z3. There is certainly an inlet grill to allow air to be drawn into the car, worth checking out to see if it's blocked or full up with muck.@EnthuZiaZT I don't actually know, I shall add that to the list of small replaceable bits to obtain soon
Edit: Google seems to suggest none of the Z3 range had a cabin air filter, can someone confirm?
