Excelente producto y servicio!!!

It's A wide band sensor. It fits how it should, it seems to be quite accurate as it is hooked up to an AEM gauge and my AFR readings are what I would expect them to be. The overall quality of the sensor is very high, the connector fit perfectly into my AEM wideband connector and it's been on there for some time now and is still doing its job. Phenomenally. As far as installation of a wideband sensor, if you need to retain your second O2 sensor, you will need to buy an additional bung drill the whole weld the bung, and then install the O2 sensor like you would any other sensor. And as long as it's not too far behind your second O2 sensor, your readings should be pretty good. Ideally you'd want The sensor to be plumbed in near your upstream O2 sensor but I have tti long tubes and my upstream sensor is not in my merge collector which seems kind of like a mishap on their end, but I digress. It's a great sensor. It does its job. It seems to be very accurate and it's a very good price. 10 out of 10 would recommend

Did not work with my AEM X-series AFR gauge. Would not recommend. The AFR gauge was not even able to read the sensor. Had to buy a real AEM Bosch replacement sensor and it works now.

Reliable!

4/11/23 - Bought mine on Sept 2022, and today April 2023, it finally gave out after numerous 200 shot nitrous passes on my LS Z. So for 7 months of use, it’s not bad at all.Seller claims to have a 12 month warranty, so I had messaged them about getting a new replacement unit. I’ll updated my review on how the seller stay true to their warranty listing.Update: 4/12/23Seller has responded and asked for my info in order to send a brand new replacement since it is still under the 12 month warranty. I will update again when I get info on tracking or when it arrives.So far customer service has been speedy!4/16/23 - New O2 Sensor received! Works flawlessly!Would honestly buy again.

I’ve purchased two of these sensors. One for Holley Sniper and one for Aces Jackpot system. Both sensors work well with no issues.

I made the mistake of just copy/pasting the part number and then clicking the first thing that I saw. Realized immediately what happened when I took it out of the box. Not Bosch. 50ft clone, probably Chinesium.It is what it is. Little disappointed but it's my fault.I will install it and see how it works. Not optimistic about lifespan, but to be fair, the OEM Bosch that it is replacing died after 6-10 hours of use.....

It's working as it should the fit is perfect, the price is reasonable...
