Third o2 sensor
I figured a used one already went through the trenches. Installed it with a bung extension. Working as it should. Let’s see how long it lasts

works as replacement for aem x series wideband
the sensor for one of my aem x series widebands went bad & would peg lean at all times. the innovate sensor was the fastest available one so i took a chance figuring it would work and it works just as well as the original aem sensor. the cable on the innovate may be a little longer than the aem one so thats a plus for anyone looking at this as a replacement too

Perfect for ECB-1 replacement
My O2 sensor was shot from my original Innovate ECB-1 gauge. AFR was displaying improperly. This is exact replacement.

2 dead in less than 4 months...
Update on this review. I contacted innovate in regards to the matter and they are going to send me another sensor to try. 5 stars for their customer service but the 1 star remains for the Bosch product. I'm holding my breath on how long this one will last... 2nd sensor in 4 months that has died. I've done everything by the book with it and it was professionally installed/calibrated. They both died in less than 2 months. The 2nd one I bought I decided to put in the heat sink to keep it away from the direct heat. The result? It failed sooner than the original sensor that came with the gauge. Garbage. Do not buy.

Part worked for about 2 months
Then went haywire and causes the gauge to totally go lean. I would like to return and replace it.

Accurate and great
As described - I wish the threads were a bit stronger. Works great. 5 stars if it would have had beefier threads that don’t strip so easy.

Fits Innovative MTX AFR

these are the real deal
I use these with an Innovate LM-2 unit on my engine dyno. The dyno is hard on the sensors, so I have to replace them often. I've tried the "no name" replacements and they just don't last at all. These from Innovate last way longer than the cheap knock offs...
