I found out that with oxygen sensors they are very sensitive and you should always buy the original part. These are aftermarket parts and they only lasted about 2 weeks. I was being charged over $400 at the mechanic just for the parts and about 300 or more to replace everything so I believed doing it myself would be a lot cheaper I found these oxygen sensors for my Kia 2012 and while they do fit they were not up for the task. I went to the mechanic after 2 weeks because my check engine light came on again and they told me that that shouldn't have cheap aftermarket O2 sensors because they are very sensitive and each sensor is rated differently for each car. As you can tell these two did not work and they got burned really easily because they were not rated for this car. These are really cheap and I say don't get swindled by the price trying to save money with this part of the car. Oxygen sensors are meant to work together to help with the emissions preventing toxins to be released from the car. These are important parts for you to not only pass your emissions test but also to do your part for the environment. If you buy cheap parts and don't replace them even though they need to be replaced you're only going to be damaging your car and their environment
