Review on Upstream Downstream Replacement 2000 2011 39210 23750 by Marcus Budd

My analysis of this Automotive sensor showed that it did nothing but add more problems to my already troublesome car. While it claimed to be a replacement part, it failed to function properly and caused a multitude of issues .The only pro was that it looked similar to the original sensor. The cons were that it was unreliable and caused further damage to MY vehicle. Avoid purchasing this product at all costs..
