Review: OEM and a good price - reputable supplier - Seem to be exactly OEM, from Sixty Auto. I've heard there are counterfeits out there, but these appear to be the same as the originals and AI says Sixty Auto has a good reputation. I read about the counterfeits after installed them, so I'm going to take one out and do a double check, but I assume they will be fine. The car runs great. I replaced them at 129,000 miles although the car was not running poorly before.
