I just picked up a 2005 X3 and am doing some research. My plan is to give it a complete tune up/service including all fluids and fitlers. My question, in keeping with the original topic of this thread, is will the carbon type filter fit in the X3 without climate control? I found two listings for cabin filters, the carbon type for vehicles with climate control, and a simple paper element for those without. Anyone know if they are interchangable?
