Engine Mechanical problem
2007 BMW X3 6 cyl All Wheel Drive Automatic 99480 miles
I want to save money by doing my own tune up on my BMW X3. It is the M series (higher performance engine, etc) and I have the VIN (WBXPC93427WF12056). I assume plugs, filters but I don't know what else. Anything to help in these tough economic times would be appreciated.
