AEM replacement
To those who are looking for an AEM wideband replacement, this review is for you! This is the exact fit replacement for your failed AEM sensor. The harness is shorter than what came with your wideband, but it is the exact replacement for my X series 30-0300. Works perfectly and is able to be read by my gauge and ECU with no errors. Stock up on a few before prices go up and never have to worry again.

Perfect fit on a 2012 Ford Focus SE
I installed this oxygen sensor on the upstream port on a 2012 Ford Focus SE and it worked out fine. The connection and length of the cable were identical to the sensor it replaced so installation was quick and easy. About two weeks before I attempted to change the sensor, I sprayed the sensor on the car with WD40 to allow the oil to penetrate the threads. I did the same about three times within the two weeks and when it came time to remove the old sensor, it unscrewed easily. Also, an O2 sensor socket is helpful for removal and installation since it has a cutout for the cable so that the socket can fit over the nut portion of the sensor. Overall, replacement was straightforward. Unfortunately, my check engin light still comes on every few days or so, so I continue to troubleshoot the cause. At the very least, I now know that the issue is not the upstream O2 sensor.

Works - 2013 F150 3.5 ecoboost
Fixed my check engine light, still off after 500 miles. Exact fit. Install wasn’t too bad, just use a big 7/8 wrench.

Not for Ford Transit
I think this would normally be fine, but my Ford Transit did not like it at all - three more codes than the original. Had to go with a Dorman/Motorcraft.

Works as advertised
Perfect replacement for my kids 2012 Ford Focus Titanium. Check engine light indicated that the O2 sensor was bad and holy moly was it right. When we pulled the old one out it was caked in carbon deposits. This one threaded in with no issues and after we cleared the stored code it has worked flawlessly! I would recommend this over other cheaper aftermarket O2 sensors. I would rather pay a bit more and have peace of mind that this will work for the long term.
