Just one caution, if your state/locality requires emissions inspections, make sure you replace the battery at least few weeks before the due date. I overlooked this and to my surprise 2 weeks/thousand miles later I still can't pass it due to couple of sensors being "not ready".

There are driving cycles published that are supposed to make your car "ready", but it may tough to execute depending on where you normally drive, and frankly speaking one would think couple hundred miles should suffice.
