I bought this sensor as a replacement for my failing Wideband from my AEM 30-0300 kit, which is the X Series AFR Gauge. I saw 2 reviews that stuck out, one that there’s a tab that makes it not fit, and another that the sensor didn’t work with displaying 4 digits to the gauge (EX: 14.70)
For the first issue, the tab really isn’t difficult to break off. I took a pick and snapped it away and the sensor fit just fine. I bet they put that there so AEM can’t make any claims against them, because it snapped away smoothly.
Second, the person who stated they can’t see 4 digits likely never set their gauge to 4 digits to begin with. There’s a button on the AEM X-Series Gauge to change from 3 digits to 4 digits, and I had no issues with this sensor reading 4 digits, and my Link ECU read 4 digits just fine from it as well.
As an LSU 4.9 replacement sensor, the fitment is perfect, the sensor wiring is about 5 feet long (compared to the AEM sensor that was about 2 feet) and it works perfectly for my AEM X-Series Gauge and my Link ECU reads it without issue. I would 100% recommend giving this sensor a shot, as it also has a lifetime warranty!

I bought these for a tuneup because they were American made and inexpensive. I was getting 15 mph on the highway with no codes before installation. As soon as they were installed I got P01131 and P01151 lean condition errors and 10 to 11 mph. Unfortunately I had waited a while to put them in and cannot return them.

MUST BREAK OFF LITTLE PLASTIC TAB INSIDE CONNECTOR FOR IT TO CONNECT INTO AEM 30-0300 harness.
Worked great for me once done.
2nd picture is what it will look like once done

Good quality and fit seems to be good. Is what the website tells you.

I bought this LSU 4.9 Lambda Wide Band O2 Oxygen Sensor to replace the Bosch Unit that came with my AEM 30-0300 – X Series Digital Wideband UEGO AFR Gauge/ Controller. I bought a Bosch LSU 4.9 after the original failed due to thermal shock. [ I had my ignition on several minutes, messing with my Tuner before re-starting my Hemi w/ headers in sub-zero weather. *You have to turn off the ignition to let the Sensor’s heater cool, first!] The Bosch replacement came with too short a cable! – I found this one on Amazon from AA Ignition, and it works just like the Bosch for less $, and the cable is long enough! A PLUS!

I Installed this part on my 2005 Mitsubishi Evolution Lancer. And it worked great for a few months now it just reads random numbers and then just reads all zeros.
I see you guys HEAVILY advertise a lifetime warranty.
THEY SENT ME A NEW ONE NO VERY EASY TO WORK WITH HIGHYL RECOMMEND

What do I like about this product? Well one the price, as an O2 sensor should not cost some $70 dollars to replace. And this one was a great price. Is it OEM? Nope not for a 2001 Ford Ranger, but it will fit and should work provided your O2 sensor bung is located in the correct position. If it’s not and positioned so that it’s jammed against the firewall of your truck, due to someone fabricating an exhaust Y improperly the good luck getting this O2 sensor to fit without relocating the O2 sensor bung. As it is a half inch longer then OEM. Which is probably the only thing I dislike is that it is a half inch longer then the OEM part. But if my O2 sensor was clocked right to begin with, it would not be a problem.
So what I dislike about this product is actually not the O2 Sensor, but the fact that I have to fix someone else’s mistake to make this O2 sensor work. Other wise it is the right part. Would I recommend buying it? For the price I paid, you bet your bottom dollar I would. As it’s a good price, with a good warranty behind it as it doesn’t get any better then a life time warranty. Least that’s what it says on the box I got.

I gave a 3 rating as no idea if it would have worked as the downstream sensor for m 2002 Ford Focus, but it is MOST DEFINITELY NOT COMPATIBLE with my car as an upstream sensor as claimed. Tried 2, 1st one seemed ok for 100 miles then TOTAL FAILURE, worse the original bad one (108,000 miles on original), so put in the 2nd and just terrible right off. My buddy – an SAE Certified mechanic for many yrs and one of the best mechanics I know said Ford, and Chevy, are very picky and to not even get the Bosch, he said for this car to ONLY run an OEM Motorcraft. Went to Autozone, spent $52 on the NTK, who makes Motorcraft, and car is running great right off. Will know for sure on this one after 100 miles but the Amazon ones no question are NOT any good for as an upstream unit for my car. Ad claimed both are the same, upstream and downstream, but not for my car as claimed in ad. Returning to Amazon.
DO NOT CHEAP OUT on upstream O2 sensors, just not worth the hassle, but I’m now really good at putting them in and can do the upstream in my car in 20 minutes. Downstream was too locked in and didn’t want to break the catalytic converter trying to get out a unit that only senses temp and does not control mixture like the upstream.

Decía que era compatible con varios modelos de medidores pero por lo menos con dos AEM que probé con ninguno senso
