2007 to 2010 BMW Z4 and BMW X3 Owners Have Option of Lifetime K&N Air Filter

The BMW X3 sport-activity vehicle comes with a new transmission for 2007. The company claims this accounts for a 6-percent gain in fuel economy and offsets the increase in power and curb weight. Another option in the BMW lineup is the Z4, a roadster with refined handling and well balanced driving on public roads.
