Buying non-dealer TPMS sensors can be a dubious purchase; If it doesn't work after installation, don't pay the cost of the sensor(s) and installation/matching to the dealer who does the installation. However, these sensors were on the higher end of the quality range, had great reviews, and cost significantly less at the dealer than similar TPMS sensors! A pleasant sight when the installation was easy and they started working immediately without any problems. Featured!
