BOSCH 15510 Premium OE Fitment Oxygen Sensor - Compatible With Select 2003-19 Chrysler, Dodge, Jeep, Mercedes-Benz, Mitsubishi, Volkswagen

If you have a Jeep get these and only these o2 sensors. I have messed around with "after market" they simply do not work. Been struggling with every nonsense problem in the world throwing insane codes, Jeep needed to be re-started constantly to run properly. Got to the point that experts saying I need a new PCM. It was just the O2 sensors the entire time.

Great Price and fast delivery. I got (4) of these (upstream and down stream) and what a difference in response and performance. My truck has about 210,000 mi. and I change these about every 80k. My truck was feeling a bit sluggish so I changed them early. I didn't have any error codes, but I know the signal from the sensor had to be slowing down. The engine now idles smoother and runs much stronger. The price and delivery time was good enough that I will be buying these for my 2007 Chrysler Aspen 5.7 Hemi.One item to note: there is a difference in the connectors on the upstream. I already knew this (the upstream is a different part No.), I just cut off the original and attached it to the new one. The down stream was a perfect match.

Muy efectivo

I had to return all 4. 3 of 4 we’re bad right out of the box. I think someone got a batch of seconds.

Seller refunded full purchase price on four of these when new catalytic converters and four of these were installed new at the same event and these all failed(along with both catalytic converters?????). Grateful for refund. replace factory parts and they all worked, don't know why all the failures. Just extremely gratteful to have these refunded!!!!!

Everything worked fine fit perfect went through inspection. Thank you very much.

Part is exactly like OEM, fixed check engine light issue ! PAIN IN THE BACKSIDE TO CHANGE Though ! Be sure to look at the manual or video for replacement help.

The sensors were in installed in February 2020 but now 1 of the sensors has failed. The 800 number on Amazon was not correct and was for another Bosch company/division. I have finally found warranty department and initially was advised they will not process as they state it needs to be through the seller. Additional phone calls have directed me to warranty department which I think will allow me to return the part directly to Bosch. I mostly have inserted lowER rating towards Amazon as they did not provide clear direction on how to replace defective part (WRONG 800 NUMBER). Generally I think Bosch will stand behind their warranty so the part itself
