ACDelco 213-3908 GM Original Equipment Heated Oxygen Sensor

todo excelente y muy buen precio

Fits perfect in manifold.

This is the O2 Sensor for the 2009 GMC Envoy, fits & functions well. The Amazon Auto Parts Search Engine Algorithm is WRONG, the correct Downstream O2 Sensor for the 2009 GMC Envoy is ACDelco 213-3908 , it's this specific part. After I installed it, the annoying, "Check Engine Light", is no longer illuminated, therefore, I fixed the Check Engine Light problem; I replaced the Upstream O2 Sensor too. My vehicle runs great now, more horsepower and better gas mileage too

Took awhile to get the old sensor off because it was rusted in. Make sure you spray the old sensor with PB Blaster while you wait for the new one to come in. Works as advertised. No more codes.

Fits 2007 H3 Perfectly, exact part
