This starter worked fine when installed. The only reason I didn't give it a 5 star rating was fitment. the hole in the bell housing is slightly larger than the starter. The old starter, OEM, was a right fit. This puts all of the strain and torque of starting the engine on the two bolts that hold the starter in. I expect this to fail at some, hopefully, distant point in the car's future. In order to retorque the starter bolts, the battery and airbox have to be removed.
