Review on ACDelco 213 3908 Original Equipment Heated by Bilal Cartwright

This is an oxygen sensor for a 2009 GMC Envoy, it fits and works well. Revain's auto parts search engine algorithm is WRONG, the correct downstream oxygen sensor for a 2009 GMC Envoy is ACDelco 213-3908, this is a specific part. After I installed it, the annoying "Check Engine" light went off, so I solved the "Check Engine" light issue; I also replaced the upper O2 sensor. My car drives great now, more horsepower and less fuel mileage.
